Just like all household appliances, dishwashers need electricity to function. Your electricity setup needs to be able to support the use of several machines running at the same time without any trouble. We are going to explain the reasons behind this breakdown right here.
THE POSSIBLE CAUSES FOR THIS BREAKDOWN:
Before you do anything to your appliance, make sure you disconnect it from the power supply.
There is a risk of electric shock.
The electricity supply enables your washing machine to work. It can be the case however that your electric plug has melted or it won't unplug any more. Make sure the plug works by plugging another device into it, for example. Reminder: you are advised not to plug household appliances into multi-socket extension leads.
The heating element heats the water inside your dishwasher. If this heating element is faulty, it may trip the power supply off. You can check whether this is what is causing the issue by unplugging the dishwasher from the power supply, then unplugging the heating element's connectors. The heating element is located behind the access cover on the underside of the appliance. Plug the dishwasher back in and check if the power still keeps cutting off. We advise you to be careful during this operation and to put gloves on because the metal on the cover is very sharp.
The door latch system is designed to switch off the dishwasher if the door is open, or to switch it on again when the door is closed. It can be the case that a little water has got in due to a fault in the door seal, which can cause a fault with the door switch (mini circuit breaker) which then cuts off the power supply. You can check the door latch system by removing the control panel with gloves, because the metal is very sharp, and then you can test the continuity of the switch using a multimeter set to the Ohmmeter position. Unplug the dishwasher from the power supply before you begin working on it.
Water and electricity do not go well together. If a hose has a puncture and liquid is able to come into contact with any electrical parts such as the heating element, the effects can be disastrous. Although, of course, the dishwasher does immediately go into safety mode and trips the mains power supply off. You should then look for the cause of this leak.
The wash pump supplies water under pressure to the spray arms. If the wash pump is leaking through its axle, it can generate electrical leakage which may trip the power supply. If this is indeed the case, then you will need to replace the pump. It is easy to find the wash pump as it is located behind the access cover on the underside of the appliance.
The drain pump enables your dishwasher to drain the water inside it. It may be that the drain pump is faulty. If this is the case, it is likely to trip the power off. We advise you to check it by unplugging the dishwasher from the power supply then removing the pump's electrical connectors. Switch the dishwasher back on and test it. If the dishwasher is no longer tripping the power off, you should replace the pump.
All the functional parts of your dishwasher are connected by electrical wiring. Each of them have a connector at the end that may be faulty due to overheating or because these have been twisted, bent, or cut. If they end up tearing or melting, they will touch the body of the dishwasher or any other element that is earthed and will thus trip your home's main power supply off.
