A washing machine that doesn’t heat water properly can be frustrating. Often, the culprit is a faulty thermostat. This small but important part controls the water temperature during your wash cycle. When it fails, your clothes might not get clean, or the machine could stop working altogether.
In this post, I’ll explain what a washing machine thermostat fault looks like, why it happens, and how you can fix it. I’ll also share some tips on choosing reliable repair services, like those offered by RePair Team, who specialise in quick and affordable appliance repairs across South Africa.

What Does a Washing Machine Thermostat Do?
The thermostat in your washing machine acts like a temperature guard. It tells the machine when to heat the water and when to stop heating. This ensures your clothes get washed at the right temperature for the best cleaning results.
If the thermostat is working well, it keeps the water temperature steady. If it’s faulty, the water might stay cold or get too hot, which can damage your clothes or the machine.
Signs Your Washing Machine Thermostat Might Be Faulty
You don’t always need a technician to tell if your thermostat is the problem. Here are some common signs to watch for:
Water doesn’t heat up during cycles that require warm or hot water.
Washing cycles take longer than usual because the machine struggles to reach the right temperature.
Clothes come out still dirty or with detergent residue because the water temperature was too low.
The machine stops mid-cycle or shows error codes related to heating.
Burning smell or unusual noises during the heating phase.
If you notice any of these, it’s time to check the thermostat.
How to Test a Washing Machine Thermostat
Testing the thermostat requires some basic tools and safety precautions. Here’s a simple way to check it:
Unplug the washing machine to avoid electric shock.
Locate the thermostat, usually near the heating element.
Use a multimeter to test for continuity. Set the multimeter to the lowest resistance setting.
Touch the probes to the thermostat terminals.
A reading close to zero means the thermostat is working. If it shows no continuity, the thermostat is faulty.
If you’re not comfortable doing this yourself, it’s best to call a professional.
Fixing or Replacing the Thermostat
If the thermostat is faulty, you have two options: repair or replace it. Repairing is rare because thermostats are small and inexpensive parts. Usually, replacement is the best choice.
When replacing the thermostat:
Make sure you get the correct part for your washing machine model.
Follow the manufacturer’s instructions or hire a trusted repair service.
Check other parts like the heating element and wiring to avoid future problems.
