Washing Machine Keeps Tripping the Electrics

It has been reported that certain washing machines trip electricity often. But, there are some simple checks you can undertake to establish the problem. However, there could be more technical problems other than what this article suggests. This is a fault you can’t really deal with unless you are professional washing machine repair engineer. Here at Repair Aid we have the expertise and equipment to deal with such repairs safely and efficiently.

Washing Machine Keeps Tripping the Electrics

This diagnostic advice and general guidelines are not model or make specific, and you need to apply your common sense and diagnostic skills to benefit from this guide. In case the problems persist, you could visit the available forums to get model-specific advice from the company engineers. Remember to disconnect all the power sources before you begin to work on any appliance.

General Reasons

The main reasons for tripping of a fuse or RCD when the appliance is the problem is normally an earth leakage or dead short. This usually takes place each time you switch on the product. Some washing machines may trip when particular functions are in use. Most laundry appliances or washing machines will point to the faulty component making the process of correcting the issue straightforward. However, non-straightforward issues will call for some basic knowledge, a meter, patience and time to resolve.


Cold weather conditions result in dampness from unheated areas such as conservatories, huts, outdoor buildings, and garages among others. Electricity and water don’t mix well, and dampness can get into components that have sensitive low voltages. The dampness could also get into the main voltage devices like control modules and motors forcing the machine to trip. This can take place during operation or when the machine is powered. Modern machines are designed for normal room temperature and indoor use. Avoid highly humid environments and low temperatures to avoid such issues.

Fuse Trips Once You Switch on the Washing Machine

First, confirm whether the plug wiring and cables are undamaged and well connected. Also, check and test for blown cables and plug tops as they may be the source of the problem. The third point is to check whether the power supply that the machine is connected to is working well especially the sockets. Some issues cannot be covered by warranties since the machine had no problem. The terminal block may also be scorched or burned out especially in older machines as they tend to melt, fail, or degrade with age. For washing machines, you could also confirm the functionality of the mains radio interference.

Door Locks and Main Power Switches

In some models, all you need to do is turn a dial to switch on the washing machine. A component may also fail when the neutral and live are in one place as this can burn or arc terminals. Safety locks make sure that the door is shut throughout the wash cycle. The door lock could be arcing internally or electrically faulty leading to an RCB unit trip. Faulty door safety interlocks can lead to tripping. Things may be complicated beyond this, and you will need more technical advice. If you need more help, please call Repair Aid technical helpline on 020 7183 6944 and we will arrange for one of our washing machine repair engineers to visit you.

Power Blows When Starting the Program

The main cause for this is faulty components that are energised when the machine is powered on. Some of these components include the heating element, motor, inlet water valve, door lock, and main power switch. Test each of them to see where the problem is resulting from and repair them accordingly.

How to Test Components

The first step is to disconnect the power before you begin working so that you can stay safe. You should have various test components like a multimeter. You can visually observe some faults, but others must be tested and replaced. If the predicament persists, don’t hesitate to contact our qualified washing machine repair technicians to avoid causing further harm to the washer.
