Re: indesit idl40s
A quick trawl through this forum will soon reveal that this is a very common fault on Indesit dishwashers.
In 99{e5d1b7155a01ef1f3b9c9968eaba33524ee81600d00d4be2b4d93ac2e58cec2d} of cases it is either the heating element or the control PCB that has failed.
As yours appears to have the ‘L’ shaped element that is visible inside the tub, it is more likely to be the PCB on your machine.
The first step is to unplug, remove the baseplate and test the element with a suitable multimeter or megger for continuity/resistance/insulation.
A couple of different PCB’s used, full serial number needed to identify. Is there a letter C after the model number?
