Try turning off the breaker to it for a few min… and then turn it back on that might reset it.

you may have a bad heating element..or temperature sensor the water temperture is not getting hot enough to let the dishwasher run. you my reset it and try running the water in the sink until it reaches hot ... then try stating the dishwasher...let me know if this helps

I have the same problem. You need to switch it off at the mains for at least 20 mins.

Sounds like it has overflowed at some stage. Ensure the filter is cleared and then rock the dishwasher backwards. Any trapped water will drain out and the safety valve will reset. i had similar and this was what the indesit technician did.

a05 is pressure switch not reset. check for blockages in the drain pump, filters and sump

Error message A01 means -Acqua stop operated due to a leak or overfill. Check if there is still water in the machine after it stop pumping. In case you still have water - your problem is with the pump or with a blockage drain line. If there is no water in the machin, it might be a water level sensor issue - stuck physically in the high level position or become defective. Try to reduced the water presure and leveled it up by the water entrance tap to the machine, it might solve your problem. Goog luck !!
