This error code refers to a time out for either fill or empty. The program control allows a set time, by which if it hasn’t received the signal that the dishwasher has filled up with the right level of water, or conversely that the dishwasher hasn’t emptied all the water properly it will time out and display E10.
Before calling out an engineer, you could try to check that the fill hose taps are turned on properly (it’s more common than you think) and there is a supply of water at a decent pressure going through the hose (faulty taps can appear to be on, but furred up inside and little or no water is getting through – this is particularly common on DIY self-tapping taps with hot taps most likely to be affected). Also, check that there is no kink in the fill hose (unlikely unless the dishwasher has been moved within the last few months or recently installed)
If the dishwasher isn’t emptying the water properly there could be a pump fault, connection fault or a blockage (often glass) in the pump.
I wouldn’t advise getting too involved with diy dishwasher repairs as they are often very difficult to work on and access to parts is very hard because of the way they are designed.
