Turn washer dryer on ok, then close door then curcuit trips

The washer tripped the breaker once and OR after the breaker was reset it ran additional loads with no problem then it tripped the breaker again.

Intermittent problems are always difficult to diagnose because the problem usually doesn't occur when you're making the checks.

If the washer ran additional loads the problem will not be an electrical short with one of the washer parts. If the lid switch had a short it wouldn't run additional loads.

if the additional loads used the same cycle as previously. A timer can have an internal short that might trip the breaker in heavy duty cycle but not the permanent press cycle.

If you have access to a clamp on amp meter, see the image below, then you can check the amp draw of the washer. The washer normally will draw about 10-15 amps at start up and about 5-8 amps while running. The house breaker for you washer should be rated at 20 amps.

If the washer is running and drawing less than 20 amps and the breaker trips then if can be a weak house breaker.

Mid cycle the washer is most likely draining or spinning and if the bearing or pump locks up then the washer may draw additional amps to try to start and trip the breaker.

The key to this problem is what the amp draw of the washer is when the house breaker trips.

To narrow this problem down, there are three places that could be causing the ( outlet) GFCI to trip, a malfunction in the washing machine, a problem with the downstream wiring (aka load side of the GFCI-other items connected on same circuit), or the GFCI outlet itself. If there isn't anything downstream, then plugging the washing machine into another GFCI outlet, or simply swapping out the outlet for a known good GFCI outlet, will identify if the outlet itself is faulty.
If the outlet trips when the washing machine isn't running and isn't even plugged in, then there's a fault in the wiring on the load side of the GFCI outlet.
If the issue is neither of the above, then running the washing machine and monitoring to see which step is occurring when the trip happens will isolate what part of the washing machine may be leaking current to a ground. It could be a certain water level, a motor being engaged, a transition step in the controller, etc
Beware some techs believe that most Washing machines or any other motor should not be on a GFCI! Should be a dedicated single receptacle. If there are other outlets on the washer GFCI, replace that GFCI with a single receptacle and put the GFCI on the next jump in order to protect other outlets.

Another item to check is ur lid switch which may have gotten moister inside and created a short_ or broken open and the rubber seal dried out over time, and the switch assembly will be exposed. water can splash onto the assembly, somehow causing the GFCI to trip. In any event, if you are having trouble with your washing machine stopping mid-cycle for any reason, test and  HYPERLINK "http://www.youtube.com/watch?v=MFsvLiuTniU" replacing the lid switch is probably a worthwhile idea, as it is cheap and easy to replace.
By the way my advice is free cuz God is good!

If your Logik LVD7W15 tumble dryer is tripping the fuse box as soon as you close the door, it may be caused by a few different issues. Here are a few steps you can try to troubleshoot the problem:

1. Check the door switch: The door switch is responsible for detecting whether the door is closed or open. If it is not functioning correctly, it can cause the dryer to trip the fuse box. Make sure the door switch is properly installed and functioning.
2. Check the thermal fuse: The thermal fuse is a safety device that is designed to protect the dryer from overheating. If the thermal fuse is faulty, it can cause the dryer to trip the fuse box.
3. Check the heating element: If the heating element is faulty, it can cause the dryer to overheat and trip the fuse box.
4. Check the wiring: Make sure all the wiring connections are tight and secure. Look for any damaged or frayed wires.
5. Check the PCB: The PCB (Printed Circuit Board) controls the various functions of the dryer. If it is faulty, it can cause the dryer to trip the fuse box.
6. If none of the above steps work, it is possible that the dryer has a more serious problem that requires professional service.

Please make sure to turn off the dryer and unplug it before attempting any troubleshooting steps. It is also important to refer to the user manual or contact the manufacturer for specific instructions or troubleshooting steps for your specific model.

This link has the part that is probably bad: Hotpoint Washing Machine Compatible Door Interlock - Part Number INT51 for bwd129 (ransomspares.co.uk)

check all the connections there could be a worn out wire

Change electronic board it is what will cause this problem if you checked all ducts an fan and still heats board is bad

reason the machine blows trip probly damaged wire unplug mach remove lid and check wires around dryer unit this is often the scource good luck

Unplug at the mains, remove lid and door catch can be released from inside the machine.

Short circuit on the door switch module

You have a fault on the machine which is a dead short or an earth leakage.

Neither can be sorted out without a set of testers and some knowledge

Unless you can get hold of a resistance checker and know how to use it call a in a repair person

A faulty heater in both a washing machine and dishwasher will trip swithes because they both cause an earth........the chances are you heater needs replacing......the reason its tripping after a short period is probably beacause the cycle doesnt start heating the water until after approx 15-20 mins depending on the cycle chosen
