What to check yourself
Step 1. Clean the drain pump filter
On front loaders it is behind a small hatch at the front bottom. Put a shallow tray and towels down before opening it: a full drum comes out faster than people expect. Unscrew the filter, pull out what is caught in it, and check the impeller behind turns freely. Coins, hair grips, buttons and underwire are the regulars. Many top load Whirlpool machines have no accessible filter at all, in which case skip to the hose.
If the cycle stopped mid-wash the water can still be hot. Give it an hour rather than risking a tray of water at 140F.
Step 2. Check the drain hose along its whole run
Pull the machine out and look at all of it. A kink behind the machine after it has been pushed back into place is the second most common cause and costs nothing to fix. Check the hose is not pushed too far down into the standpipe either, which makes it siphon and blocks itself.
Step 3. Test the standpipe or sink trap
Take the hose out and pour a jug of water down the pipe. If it backs up, the blockage is in the house plumbing rather than the appliance, and nothing done to the machine will help.
Step 4. Listen to what the pump does
Start a drain or spin and listen. A pump that hums without moving water has usually failed. Complete silence points at the pump, its wiring or the control board. Worth noting before you call: it is the first thing you will be asked.
What a technician will look at
Described so you know what you are paying for, not as steps to repeat.
Replace the drain pump
If the filter is clear, the hose is open and the standpipe drains, the pump has failed. On most Whirlpool machines this means tipping the appliance and working on a live circuit.
When to call a technician
Once the filter, the hose and the standpipe are ruled out. Call sooner if the machine trips the breaker when the pump should run, or if there is a burning smell from underneath.
What the repair costs
| Repair | Part only | Fitted by a technician |
|---|---|---|
| Clearing the filter, hose or standpipe | - | Free |
| Drain pump replacement | $20 to $100 | $150 to $400 |
| Diagnostic call-out if nothing is found | - | $70 to $130 |
A new machine of the same class runs $500 to $1,500. Once a quote passes about a third of that on an older appliance, the repair stops making sense.
Codes people confuse this with
Questions people ask
- My top loader has no filter hatch. Where is the blockage?
- Many Whirlpool top loaders use a self-cleaning pump with no serviceable filter, so the usual suspects move outward: the drain hose, the standpipe, and the pump itself. If the hose and pipe are clear, it is a pump job rather than something you can reach.
- Could too much detergent cause this?
- Yes, and it is missed constantly. Heavy suds stop the pump moving water and the machine reads that as a drain fault. If the drum is full of foam rather than water, read the Sd page first and halve your dose.
Which machines this applies to
Applies to
Whirlpool front and top load washers, and the same fault on Maytag, Amana and Kenmore machines built on Whirlpool platforms. Older displays show Drn instead of F9 E1.
