This is another form of fault indication on less sophisticated washing machines. Older Indesit and Hoover washing machines used to do it. If the selector knob is clicking round all on its own then the washing machine has probably aborted the programme due to a fault.
You can get a clue as to where the fault could lie if you know where on the program the clicking starts. If it washes OK, but then starts clicking round during the rinses it could be a problem with draining the water (check the pump filter). If it starts clicking round after several minutes it could be because it’s not heating up the water.
Unfortunately though, there are so many causes for the timer selector knob clicking round that even engineers can sometimes have problems tracing the cause. Even a low insulation reading on the heater or motor can cause it – as can a faulty PCB control module, or a fault on the thermistor (thermostat) or even just a faulty connection somewhere.
If your washing machine selector knob (dial) clicks round continuously and you can see some of the lights flashing, or one or more option lights have lit up, then make a note of which lights are flashing and which option lights are lit as described here – washing machine lights flashing.
I have many articles on appliance error codes, which give further insight into why error codes aren’t readily available as well as explaining why many aren’t much use to you anyway. I’ve put up the meanings of some of the more common error codes too – White goods error codes
Resetting an Indesit washing machine
Some older Indesit washing machines have a bizarre procedure to reset the program once it is started. Most modern washing machines have a cancel button that you press for a few seconds and the washing machine will abort. With some earlier Indesit washing machines, if you move the selector knob after the program has started it will just click all the way round to try and find the original program and continue with it.
So to reset one of these Indesit washing machines with a selector knob (but no cancel button) you need to do the following –
- Turn the washing machine off with the on off button.
- Turn the selector knob to a dot, or any off position
- Turn the washing machine back on and watch for rapid flashing on the neon light
- Turn the washing machine off and select the new program (or maybe spin)
- Turn it back on and the new program should start
NOTE: Resetting the timer selector knob as shown may stop the clicking round, but if your washing machine dial keeps turning and clicking after it’s been reset then it needs investigating. Unfortunately this type of error detection is extremely crude and gives no indication what it could be other than “something” is wrong.
