My dishwasher is causing the RCD to trip on my fuseboard. Have had an engineer out who diagnosed a crack in the motor housing that is allowing water to leak on to the wiring underneath. He repaired it with some sticky stuff but that only held for 30 mins. When I called him back said needs new motor housing will phone you with estimate. No further response in spite of 3 reminders, makes me think he doesn't want to do it. Tried other firms but nobody wants to repair integrated dishwashers! Is it possible to DIY? Can't even find the model number on your site. It is only 3 yrs old.

not necessary-- yet-- to buy a new unit
tripping the rcd is an indication of earth leakage which could amount to water in the wall plug across pins, moisture across the power board, water in the motor, faulty heater element
what you need is an accredited electrician to run tests on the system to find the reason for the earth leakage that is tripping the rcd
the rcd works from microvolts and operates in nano seconds to prevent electrocution of the operator
testing before buying may save heaps of cash
This can be due to the fact that the heaters draw up more current than required and so trips the circuit. it will be important to remove and check the heaters, check if the contactors are faulty that feed supply to the heaters. Also if the trip is a ELCB- then with some leak in the circuit , motor, heaters, the circuit will trip. Hence check the electrical, check the ground on your dishwasher. Use an external ground and check
My dishwasher a diplomat 12 program (hja8640) was doing exactly the same where every now and again when turned on at the plug it would trip. After engineers coming out several times and failing to fix it, they condemed it. New one was supplied, however did exactly the same thing. The electrician came back, checked the RCD power breaker and this was fine. It was then discovered that some dishwashers and washing machines send out a lot of earth leakage, combine this with other appliances on in the house can be enough to trip.
Soloution. The electrician removed the kitchen circut from the RCD breaker and intalled another breaker RCD just for the kitcehn loop, this therefore means that the kitchen has a seperate trip from the rest of the house, and touch wood, has solved the problem. This mind you has taken about three months to work out so i hope it saves you some time.
Has the door got any heavier, as mine started tripping the electrics when a spring broke and short circuited the connections.
f so you will have to get the spring out, from the underneath is best and replace it if you want the door to work correctly again. On mine the second one went a month later.
i had this probem and apparently there's a 'float switch' in the bottom of the machine. This switch is a safety cut off and when activated can not just stop the machine but trip the electrics in the house. the reason for it activating is when food clogs up the drainage bit water can not drain and fills up the bottom of the machine. this then activates the 'float switch' as a kind of safety cut off.
the way to sort it is to disconect the machine from the mains and drain and water. empty the clogged up food from the drain bit. then tip the machine back and a load of water will pour out (may need a load of towels for this bit or take the machine out the back and do it)
once this is done, plug it all back in and give it a try - works for my machine, good luck.
