My DI 67 Dishwasher ever now and then trips the RCD mains circuit. Does anyone know why? I only use the machine once a day and it is on normal settings, not the intensive settings. I've also checked that nothing is blocking the washing or the pipes at the back. Looks like a heating problem. But not sure. Have to wait a few hours before trying and even then it may still trip the RCD circuit. Any ideas what maybe wrong?

rcd units trip from the milliamps that are in a short
it trips the rcd to prevent electrocution and acts in nano seconds besides being a circuit breaker for excessive current
the trip can be from moisture allowing a current leakage to ground or some other simple operation
I suggest that you get in a qualified electrician / bosch service technician to find the reason for the problem rcd
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
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.
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.
