I’m getting an E3 fault on the above D/W. This seems to be a heater/stat fault. I’ve tested the heater and thats ok. It has two stats, will I need to change both? Or could someting else be causing the fault?
According to the service manual, Error E3 is a faulty pressure switch or system.
My engineers advise it is common for the pressure system to gunk up which causes the unit to heat too quickly and trigger the E3 fault. I would check the pressure system first to be sure, but yes otherwise, change both the safety stat and the thermostat.
