Tumble dryer stacking kits

 If you want to stack a tumble dryer on top of a washing machine you need a stacking frame or stacking kit. If your washing machine and tumble dryer are the same make, the manufacturer should have designed a frame specifically for them. There could be details of such a kit in the instruction book of the dryer.

Universal tumble dryer stacking kits

There are universal stacking kits available that are supposed to connect any tumble dryer to any front loading washing machine, which may be cheaper than the manufacturer’s although they might not be as snug a fit. You may prefer to try a universal stacking kit if your washing machine and tumble dryer are different makes or if you find the manufacturers kit too expensive.

As with all “universal fit” products there is the potential for it to not be a “perfect” fit but if the makers say they connect all tumble dryers to any front loaders then they should do so satisfactorily or you will be entitled to your money back. Pay close attention to the sizes of appliance they quote to make sure yours will fit.

Why do you need a stacking kit?

Many people stack their tumble dryer on top of the washing machine without using a proper frame. This is not a good idea. There are two reasons why you need a stacking kit. The first is because the tumble dryer could potentially get thrown off the washing machine or merely vibrate off during a particularly boisterous spin. Although these days washing machines are much better at controlling out of balance spins (many tend to refuse to spin a load that it detects is not well balanced) nevertheless it is still possible for a particularly awkward or unbalanced load to cause the washing machine to leap about or jump up. In this scenario a tumble dryer freely standing on top could be thrown off damaging the dryer, surrounding objects or even people.

The second reason is that a person could potentially pull a dryer on top of themselves if they pulled down on its open door. This scenario is less likely though. The concern is aimed more at children, but it’s possible to imagine someone stumbling near by and grabbing hold of the dryer door only to have it fall on them.

    I know you wouldn’t ask if it wasn’t something you felt you needed to explore but I would be extremely surprised if anyone made a stacking frame which allowed a dishwasher to sit on top of a washing machine.

    If the dishwasher leaked it could potentially soak the washing machine beneath and cause physical and or electrical damage.

    Dishwashers also tend to be a different shape and depth than a tumble dryer which tends to be quite similar to a washing machine so the dishwasher is likely to be a poor physical fit.

    The biggest problem is that the drain hose for the dishwasher would be far too low because the plumbing would be a few feet beneath it. This could allow water to siphon out during use causing the dishwasher to malfunction as this washing machine troubleshooting section describes – washing machine constantly fills with water and goes down the drain

    Can these stacking things be used for stacking free-standing fridges and freezers atop each other?

  3. avatar says

    That’s an interesting idea. I’m not aware of anything available to do that. There’s no way a washing machine / tumble dryer stacking kit would be suitable because of the difference in shape and size of the appliances.

    If you just stacked the fridge on top of a freezer, in theory (if it was a stable fit) they could be OK because they don’t move or bounce around. However, there would be a danger of the top appliance being knocked off. The arrangement would be particularly unstable when the door of the top appliance was opened as any leverage on the door could topple it on top of someone. Also, if the door was opened but then closed again and you tried to open it again shortly after then the door tends to be extra hard to open as it creates a type of vacuum. This could also cause the top appliance to fall off if someone pulled on the door but it didn’t open and instead pulled the appliance forward.

    Having said all that, I have this arrangement in my garage where I have a free standing upright freezer with a free standing fridge on top. The freezer is slightly larger so the fridge stands firmly on top without the feet being precariously close to the edge. Everything works fine and feels stable.

    following your reply to Bruce Girvan about the dishwasher on top of a washing machine, I have the same issue. I want to install a dishwasher in the kitchen and the only room left would be on top of the washing machine. is there any plumbing solution to avoid the dishwasher to malfunction ?

  5. avatar says

    Jose: The main issue apart from stabiity and leaks is the drain hose. A drain hose on a washing machine or dishwasher needs to go up well above the level of the water inside the machine to prevent siphoning.

    The waste water pipe is usually near floor level and extends 2 – 3 feet up the wall where the drain hose is then placed. To position the waste water pipe in the correct position for a machine elevated 3 or 4 feet high it would need to be similarly elevated which depending on the siting could be undesirable. On the other side of the wall the pipework would run outside at about 5 feet above ground and would look similarly bad.

    Personally I feel it’s a bad idea. Have you looked into having one fitted into a kitchen cupboard. You can get built in dishwashers that take up just one cupboad space or small dishwashers – or even worktop dishwashers that drain into the sink. You could regain the cupboard space by having one fitted above the washing machine.

  6. avatarJose says

    thanks for your prompt reply. Now I understand what the technical issue is. I thought I could connect the drain hose from the dishwasher to drain into the sink, like the washing machine already in place.
    I wish I could consider that option (take kitchen cupboards apart), but this is not my flat I am just renting it for a year or so.

    Jose: If the drain hose was extended so it was long enough to be tied up at the back of the dishwasher but then run into the sink it might avoid the siphoning problem. If the drain hose just runs downwards to the drain or as in your case to the sink then because the water inside the appliance is higher than the end of the drain hose it can just run out through gravity.

    If the drain hose is forced to go up first, then is allowed to drop lower then water should only run into the sink if it was pumped up 3 feet or so before running down to the sink.

    However, if the end of the drain hose is lower than the level of water inside the appliance it is possible for siphoning to occur because the pump can start off siphoning in the same way as you could by suckig the end of the hose. Once water has started to run down a pipe it will continue even after the pressure that started it has gone (this is what we call siphoning). It would depend exactly how the appliance works. If the machine started filling whilst water was still running out of the machine (if siphoning has been started) it is possible under the circumstances we are discussing that water would run into the machine but go straight down the drain and the appliance would be stuck in a never ending filling and draining cycle.

    You would only know for sure after trying it out.

    You would need to double check if looking into a worktop dishwasher. They are very small though so possibly unsuitable. I can’t say for sure, but I think they may not have a normal pump, I think they may have a valve that opens up when it needs to drain using the wash motor. I know dishwashers from the past used to have this arrangement until modern dishwashers started to have a separate pump similar to a washing machine pump.

    As worktop dishwashers are designed to sit on a worktop and many will pressumably drain into the sink at the side I suspect they may have the drain valve instead of a pump, which would not allow any water out of the machine unless the machine was wanting to drain.

    No one should assume this is the case though and should check they are suitable for draining into the sink.

    I have a dryer that has a larger surface area than my washing machine, I really want to get a dishwasher but the I can only get one if it the dryer sits on the washer and the dishwasher goes where the washer is now.

    Although obviously they won’t stack as the dryer is too big to fit on the washer. Can I stack a dryer on the dishwasher? (if I buy one big enough!)

  10. avatar says

    Nosnik: I would have thought that if the tumble dryer is perfectly stable it should be okay on top of the dishwasher. Dishwashers do not move whilst in operation unlike washing machines where it is essential to have the dryer fixed to the washing machine.

    However there is one potential danger which you should be aware of, which is that if the dryer is not secured then anyone opening the dryer door could potentially pull the tumble dryer on top of them if they put any leverage on the opened door. Clearly this is of more concern where they are children around. It is hard to imagine anyone actually doing it but it is never the less a warning I must pass on.

    In the news today a small child has been killed after pulling an unsecured television onto themselves, which reminds us that unexpected tragic accidents do still happen. Of course a child as small as this is unlikely to be able to reach the open door of the dryer on top of the dishwasher but it’s up to you to assess the situation. Apart from this theoretical possibility I can’t think of any other problem.

    Dear Washerhelp,
    With regard to the discussion on stacking a dishwasher over a washing machine, can you please advise a bit more on the assembly part :
    – do we definitely have to use a stacking kit?
    – Is simply putting one on top of the other, out of the question?
    – There is a 4 inch gap between the walls and the appliance (a nice washing-machine space with water in/outlets has been provided). Can I use reverse clamps (between the wall and appliance) on two sides to hold the appliance tightly in place?
    – what about placing the washing machine on top of the dishwasher?

    Thanks in advance for your help.

    Sebastian: As discussed in detail over several of my comments above I don’t think it’s a good idea to stack a dishwasher on top of a washing machine. There’s no stacking kit available that I know of and I can’t imagine any stacking kits other than ones designed to stack a dryer on top of a washing machine.

    Stacking a washing machine on top of a dishwasher would have the same problems, which are the plumbing would be too high to pump the water out to so you’d have to have the waste water pipe several feet up the wall, total instability, and the danger of leaks running on top the appliance below.

    What about stacking a condenser tumble dryer on top of a washing machine….is that possible?

  14. avatar says

    Frenchjoy: I would expect they should still be making stacking kits to stack a condenser tumble drier on top of a washing machine as the reason they are stacked is only to do with saving space.

    However, now you mention it it’s something I haven’t really thought about. It could be impractical to stack a condenser dryer on top of a washing machine because it would put the drawer where the condensed water is stored out of reach.

    This drawer of course needs emptying after each use and a stool may be required to be able to reach it from the top of the washing machine.

    A quick check on my 4Washerhelp spares site shows that there are some stacking kits designed for vented and condenser dryers – Search for stacking kits

    I have just bought myself a new condenser tumble dryer and due to lack of space, would like to purchase a stacking kit so that I can place this on top of my washer machine but I cannot seem to find any product. My tumble dryer is a Hoover VHC381 8kg condenser and my washing machine is a Hoover HNL7166 6kg Nextra Optima. Can you please advise me on the product name / code and cost for this? Thanks so much!

    I have a top-loader and had a cupboard-maker build me a simple but steady frame (which ended up not only being the most practical solution but by far the neatest, safest and cheapest). Basically equally to a tall/narrow table. Fitted the tumble dryer on top of this and have worked as such for the past 5 years. Should work for anyone.

    Slightly off-topic – but could you advise if the average freestanding dishwasher (60cm wide) is capable of supporting the weight of a Baby Belling oven (47cm wide x 37 deep) stacked on top?

    Many thanks in advance for any advice.


  18. avatar says

    Probably Dave. Don’t know if there are any possible issues with heat from the oven or not though and you’d need to be aware of the possible risk of the oven being pulled over onto someone via the door as a potential hazard.

    I have a Whirlpool washing machine with a depth of 50 cm and I want to buy a Siemens tumble Dryer with a depth of 60 cm.is it possible to use a staking kit to put the Siemens Dryer on the top of the washing machine although they have a different depth dimension?
