Washing Machine Keeps Blowing Fuses? (What to Do)

For the most part, washing machines can work reliably. However, there are instances when the washer can fail to power on, for example, if the fuse blows and so does each replacement.

Why causes the fuse to blow? Why does each replacement keep blowing and is it even a fault that you may be able to fix yourself?

This post lists the possible reasons why you may have your washing machine fuse blowing and what you can do to fix it.

Quick Answer

If the fuse keeps blowing then there is probably a short in the cabling or the washing machine.

The fuse may blow immediately after a washing machine is switched on or at some stage during the washing cycle. Note when the fuse blows as this can help you identify the fault faster.

Read on to find out the possible causes, what checks you can do, and what fixes can get your washing machine working reliably again.

Why Does the Washing Machine Keep Blowing a Fuse in the Plug?

Note: Before carrying out any repairs, make sure the washer is disconnected from the wall outlet to avoid electric shocks that can cause severe injury or death. Always seek the services of a qualified washing machine technician.

There are several possible reasons why the washing machine fuse can blow.

#1. There is a Power surge

The fuse can blow in the event of a power surge that causes an overvoltage condition which increases the brightness of the lights as a result of the high current draw.

This can damage the washer circuitry too in addition to the fuse blowing. Replace the fuse first and check if the washer powers on successfully.

#2. The Power cord may be Damaged

A short in the power cord as a result of a cut or kink may result in the shorting of the wires underneath the insulation.

The fuse blow may be instant or random with unpredictable delays depending on if the individual wires in the power cord are shorting at that moment or not for example if the cord is moved or not.

When there is a short in the power cord there’ll be a burnt rubber smell.

Inspect the power cord for any burn marks. Replace the power cord and the fuse. Check if this stops the fuse from blowing.

#3. Failing heater element. A faulty heating element such as when there is a short between the element and the ground/ earth connection can also cause the fuse to blow.

In this case, the fuse will usually blow when the heating part of the cycle starts.

Replace the heating element with another of the type recommended by the washing machine manufacturer or else the fuse will keep blowing.

Is it Safe to Replace the Fuse and Use the Machine?

Yes, provided you have identified the underlying fault, fixed it, and replaced the fuse. Even then it is advisable to monitor and supervise at least one wash cycle just in case the fuse blows again.

Find out why the fuse is blowing and address the underlying fault. It might be because there is a short in the power cord, a surge, or other. Fix this before replacing the fuse.

Contact a qualified washing machine technician to support you on this.

Symptoms of a Fuse Blow

Popping Sound and Blank Display

You may hear a “pop” sound when the fuse blows. When the fuse in the washing machine blows, the electricity supply to the washer is interrupted and the washer display will stay black.

Fuse Location

Depending on where you live, the washer may have a fused-style plug. Check the top plug for the fuse and test it with a multimeter set to measure continuity to confirm if the fuse has blown or otherwise.

Closing Thoughts

If the washing machine fuse keeps blowing, it could be that the power cord is damaged or the heating element is failing among other reasons.

Try to establish if there is a specific action that leads to a fuse blow as this can help you get to the underlying fault faster.
