How to Fix a Washer That Overfills


If your residential washer overfills or overflows during operation, a clogged water level hose or faulty water level switch is usually to blame. The water level switch, also known as a pressure switch, is designed to regulate the amount of water used to fill the washer tub during a washing cycle. When the hose is clogged or the switch is failing, the washer doesn't know when to shut off the water. Disassembling the control console allows you to access the water level switch and connected hose for troubleshooting or replacement.

Things You'll Need

  • Screwdriver
  • Soft towel
  • Disconnect the washer from its electrical supply; unplug the machine or switch the corresponding circuit breaker to the "Off" position. Pull the washer away from the wall to access the back of the control console.

  • Remove the screws securing the control console to the top panel; these screws are on the back or sides of the control console in most washer models. The type and number of screws varies by brand and model.

  • Pad the top of the washer with a soft towel to prevent the enamel from sustaining scuffs or scratches. Fold the console forward so that the controls are resting on the towel.

  • Remove the protective panel shielding the internal control console components; take out the screws holding the panel to the console. Lift the panel from the console to reveal the water valve assembly and water level switch components.

  • Look to the right of the water valve assembly to locate the water level switch. Detach the clear plastic hose from the water level switch component. Blow through the hose to clear it of any blockages.

  • Reverse the disassembly process to reassemble the control console. Run a regular washing cycle to test the water level switch.

  • Replace the switch if the washer continues to overfill. Disassemble the control console to access the water level switch. Disconnect the clear plastic hose and wiring from the component. Pry up the retaining tabs that hold the switch in place. Reverse the removal process to install a new water level switch.
