Hotpoint D/Washer FDUD4812 new heater blown.

[subs]

S/N 204234756
Fitted a new heater to this dishwasher a month ago after A10 error and the thermal fuse on the new heater has now blown (A10 error) showing again. Any ideas what could be causing this to happen. Customer said its been washing fine for the past month.

Thanks

customer not bothering to clean filter maybe? either that or a duff circ pump at a guess.

Thanks for reply.
Wash pump is ok but the filter was pretty gunged up with fat. Can something like that cause it to blow?
Funny thing is, I’ve just been to another one of these dishwashers and the wash motor has gone yet its still been heating the water (customer was still trying to use it) but hadn’t blown the heater.
Interested to hear how others would deal with this?
Just fit a new heater after cleaning the filter and advise customer to keep it clean and then keep fingers crossed?
Or
Tell customer it’s their fault and charge them to fit a new heater?

Thanks
