UK Appliance Repair Questions? Ask a Technician for Answers ASAP
Hi, welcome to Just Answer. My name is ***** ***** I look forward to helping you! You probably have a fault in the heater circuit. Were the dishes getting clean? Was the water getting hot and steamy? Can you please double check the model number from your appliance, please?
Intermittently working is most likely the result of a faulty control module. I suspect it will need to be replaced. The model you posted is not coming up for me to get you a link, though.
