Hotpoint FDW20 Popped the break now wash and drying flashing

Hello again,

Not having a great week with dishwashers, my mums packed up the day after mine!

symptoms:

She put it onto a intensive wash 65′ to clean some particularly dirty pots (program A)

after approx 30 seconds of the machine filling it popped the RCB for the house! ever since this when turning on the machine on any program the unit fills with water ok, then it starts to drain again, but with “wash & drying lights both flashing quickly (once every .5 seconds? ish…)

I have been under the unit, all is dry all cabling is fine no loose connections nothing.

I guess the heating element is bad and this is what tripped the mains in the first place, but ive run a multimeter over it and it seems ok? very odd
any help would be great.
