Washing Machine Overfilling With Water

The washing machine is one of those appliances that you can’t really live without. If you’ve ever experienced life without a working washing machine, you’ll know how hard and time-consuming it is washing clothes by hand or taking them to the launderette.

If your washer keeps overfilling with water inside the drum, our helpful advice centre article will get that ever growing laundry pile in control and save you that expensive call out charge.

Cause 1

Pressure Switch

The pressure switch on a washing machine identifies the water level inside the drum and then relays the information back to the control board. It then stops or allows more water in by controlling the water inlet valve.

Safety First! Please make sure that you have disconnected the appliance from the mains before beginning any repair.

  • If your appliance is overfilling with water the pressure switch can be the offender.
  • Carefully check the switch for any signs of damage or broken terminals.

If the pressure switch needs replacing don’t forget to check out our extensive range of spares here to help restore your appliance.

See our diagnostic video for more information.

Cause 2

Pressure Hose

The pressure hose is fixed below the pressure switch unit and air will pass through it. If your washer is overfilling - the tube may be the culprit.

Safety First! Please make sure that you have disconnected the appliance from the mains before beginning any repair.

  • Depending on your model, locate and examine the pressure hose - you are looking for visible signs of damage such as holes, tears or a buildup of debris.
  • If there is a build up debris pour some warm water down the hose to help remove any blockages.

Cause 3

Pressure Chamber Blockage

A common reason for an overfilling washing machine is a blocked pressure chamber. The pressure chamber fills with air as soon as the washing machine starts filling with water. See how to identify a fault with your pressure chamber by following our steps below.

Safety First! Please make sure that you have disconnected the appliance from the mains before beginning any repair.

  • Remove the pressure chamber and inspect it for a buildup of debris.
  • Clean any blockages, refit and test your appliance.

If the pressure chamber is damaged it will need replacing, don’t forget to check out our extensive range of spares to help restore your appliance.

Cause 4

Water Inlet Valve

The water inlet valve allows water into the washing machine so it can wash the clothes. Occasionally the valve may fail and allow water to enter; this can occur when the appliance is turned off and left overnight.

To help identify the fault you’re currently plagued with see our tips below which could bring your appliance back from the dead.

Safety First! Please make sure that you have disconnected the appliance from the mains before beginning any repair.

  • Locate the water inlet valve at the back of the machine and remove the water inlet hose.
  • Check the water supply pressure is not set too low, as the inlet valve will only function above a set minimum pressure.
  • Look for any residual water inside the drum, if it’s clean water the fault is most likely the water inlet valve.
  • Inspect for a buildup of gunk inside the inlet valves filter and clean it out.
  • If you find dirty water inside the washer drum? This is usually caused by water flowing from the sink pipes into the washer.

If your washing machine is still overfilling and you have confirmed the solenoid valve is at fault then it will need replacing - browse our online catalogue to get the part required.
