Dishwasher trips the house towards the end of the cycle

[schambers]

Hi
I have a Becko dishwasher for about 5 years, only used twice a week and we always rinse the plates and cups before they go in so it has been well looked after.
When I put it on, after about an hour towards the end of the cycle it always trips the whole house.
Any ideas on how to fix? or how much it will cost?

I assume your dishwasher is tripping the RCD main switch in your consumer unit.
I had this same problem with a washing machine.
I traced it to a minor water leak dripping straight into the motor windings (!) which caused my RCD to trip after an hour or so. Fixing the leak stopped my RCD tripping.
I’m not familiar with dishwashers though- have you looked underneath it for signs of a water leak?
There are other possible causes of your problem and no doubt others will come along and advise.

What im doing now is turning it off just before the dry mode (before it trips out)

Could be insulation breakdown in the heater drying element causing your RCD to trip.
Remember your RCD is doing its job of telling you there’s something wrong that needs to be fixed.
If you’re not confident about pulling apart your major domestic appliances, you might consider calling in a professional repairer to sort this one out.
