Hi I have a whirlpool diswasher which is about 7 uears old which has blown the fuse (and the mains trip) half way through a cycle. Replaceing the fuse has resulted not resulted in the restoring of power to the unit. Is there anything simple I could check (in line fuses etc.)? Cheers

Retest the breaker. One side can trip without moving the handle. This will stop 240 to the element but still operate everything that operates at 120 volts.

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

If your Whirlpools over there are like the older ones here in the U.S., you may find that there is a thermal fuse mounted just above the circuit board. If there is one, turn off the power to the unit, pull off the 2 wires connected to it and check it for continuity with a multimeter. If that fuse is blown, nothing works as it controls all power to the unit. Replacement fuse kits (at least here in the U.S.) are readily available on ebay for a fraction of the price that an appliance parts store would want. By looking on ebay for "Whirlpool dishwasher fuse" you can see what the fuse assembly looks like, and if identical to yours, purchase one. If you do buy one, follow the installation instructions exactly by using the supplied wires on the new fuse and the screw terminal block to make the connections. If you don't use the new wiring and connection block and simply plug the new fuse to the old connectors, it will simply blow again in a short time.

The problem is in the magnetron or the inverter board.

Try looking at the fuses in the fuse box some of them might be blown and if they are then you probly have short somewhere in your car (replaceing the blown fuses might help)

Some dishwashers have a thermal fuse located behind the console attached to the main board It is always helpful to include model number off unit as Sears does not make any appliances, they just sell them made by other companies with the kenmore name on them. You could have a GE, Whirlpool, Frigidaire, etc....

It doesn't work at all If your washer doesn't seem to work at all, check these: No power Lid switch No power Check to see whether power is getting to the washing machine. Is it plugged in? Has a fuse blown or is a circuit breaker tripped? Lid switch If the lid switch is defective, your washer can't spin and may not function at all. The switch is inside the washing machine main housing near the door frame. Often you have to raise or open the top or front of the washer to get to the switch. If it's defective, you need to replace it. Some machines have a special lid-switch fuse near the lid switch, inside the control panel. If this fuse blows, the unit won't fill with water until you replace the fuse.

Hi,
It could be that the heater is faulty - or the trip switch is worn out causing short cycling.
Does it sound like it is heating properly and getting on with the job - or does it sit for a long time doing aparently nothing?
Could also be the timer / programmer is mechanically damaged, or a component on the main control board, but most likely a heating issue.

Thermostat controls heat. There is also a motor centrifugal switch, in the element circuit, that the motor closes to insure the motor is turning. Try another heat setting. There is more than one thermostat. You may have blown the 'thermal fuse' too, which requires replacement.
It is possible that your element has failed also.

Tripped high limit. Must clean the lint filter and the exhaust vent tube and all the way in to the dryer. Hot air exit is restricted.

With the symptoms you describe i would suspect a intermittent heater element fault as you are getting earth leakage current which is tripping the whole supply rather than a current overload which would just trip the socket circuit breaker. Get the heating element checked over first as this is the most likely cause.
