What to Do When a Washer Won’t Drain

A washing machine that won’t drain can be a significant inconvenience. Fortunately, there are steps to troubleshoot and resolve common drainage issues before calling a professional appliance repair service. Follow this guide to identify potential problems and determine the best course of action.

Checking for Clogs

Clogs are a common cause of drainage problems in washing machines. Start by examining the drain hose for kinks or obstructions. Remove the hose from the back of the washer and inspect it for any blockages. Run water through the hose to clear any debris.

Next, check the drain pump filter. Many washers have a filter that can become clogged with lint, coins, and other small objects. Consult the washer’s manual to locate and clean the filter. Be prepared for some water spillage when removing the filter, so keep a towel or bucket nearby.

Inspecting the Drain Pump

If the hose and filter are clear, the issue may lie with the drain pump itself. The pump can become clogged or broken, preventing the washer from draining properly. Listen for unusual noises during the drain cycle, such as humming or grinding, which can indicate a problem with the pump.

To inspect the pump, unplug the washer and remove the back panel. Locate the pump and check for visible obstructions. If none are found, the pump may need to be tested for functionality. A multimeter can be used to check the electrical continuity of the pump. If the pump is faulty, it may need to be replaced.

Examining the Lid Switch

Top-loading washers have a lid switch that stops the machine from operating when the lid is open. If the lid switch does not function, the washer may not drain properly. Check if the switch is working by pressing it down manually. If the washer begins to drain, the switch may need to be replaced.

For front-loading washers, a door lock mechanism serves a similar function. Confirm the door lock is engaging correctly and that there are no obstructions preventing the door from closing completely.

Verifying the Water Level Control

The water level control, also known as the pressure switch, senses the water level in the washer and signals when to drain. If the pressure switch is faulty, the washer may not drain correctly. Inspect the air tube connected to the pressure switch for blockages or damage. Blowing into the tube can help clear any obstructions.

If the tube is clear and the problem persists, the pressure switch may need to be tested and replaced. This component can usually be accessed by removing the top or control panel of the washer.

Checking the Timer

The timer operates the washing machine in different cycles, including draining. A malfunctioning timer can stop the washer from moving on to the drain cycle. Listen for any unusual sounds coming from the timer during the wash cycle.

If the timer is suspected to be faulty, it can be tested using a multimeter. If no continuity is found, the timer may need to be replaced.

Inspecting the Drain Hose Installation

Improper installation of the drain hose can cause drainage issues. The hose should be securely connected to both the washer and the drain pipe. Confirm that the hose is not inserted too far into the drain pipe, as this can create a siphoning effect and prevent proper drainage.

The drain hose should also be installed at the correct height. Most manufacturers recommend that the hose be elevated between 30 and 96 inches from the floor. Consult the washer’s manual for specific installation guidelines.

When to Call a Professional

If all troubleshooting steps have been exhausted and the washer still won’t drain, it may be time to call a professional appliance repair service. Persistent issues with the drain pump, electrical components, or internal mechanisms require expert diagnosis and repair.
