Sample of the planned case interaction

Likely causes

  • Drain filter blockedan internal blockage is possible
  • Drain pump failingit can't clear the water in time
  • Pressure switch faultit misreads the water level
  • Drain hose kinkeda kink restricts the flow

Verdict — worth fixing. The arithmetic is shown before you pay.

How a case works

Every case has the same shape.

The shape is the product: a symptom becomes a decision you can act on today. One thing to read at a time, and the next check is never in doubt.

Sample checks, in order

2 of 3 shown

External checks first. Internal work stops here.

Check 1

5 minutes · torch

Inspect the reachable drain hose without moving the washer. For WFW9400SU00, the manual supports external drain checks.

This checks: visible drain hose kinks. Hidden restrictions remain possible.

Check 2

5 minutes · torch

Look at the household drain — opens after Check 1.

Symptom in

Search the symptom or error code for a guide. The F21 pilot accepts model text; photo reading is not available.

Likely causes, ranked

Each concern has a reason. In the pilot, check outcomes change the order without pretending an untested fault is ruled out.

What we cover

Major appliances, plumbing and electrical basics inside the home. If we can't rank it honestly, we say so.

Parts for your model

The planned Repair Pass shows parts only after a confirmed cause. The free pilot does not identify or recommend internal parts.

The verdict

The arithmetic, written like a sentence a person would say.

No inventory sits behind the answer, so a verdict can end a case. Every one is fix it, fix it but expect the next failure here, or replace it.

Sample verdict

Fix it yourself

$34

about 45 minutes, one screwdriver

A technician quotes

$180–$260

for the same job

A new machine

$520

of this size

Drain pump $34, about 45 minutes, one screwdriver. A technician quotes $180–$260 for the same job. A new machine of this size is $520.

Fix it

The stop line

Some jobs aren't yours to do.

When a path reaches something dangerous, the checks stop. You get what to say to a technician, what to ask, and what a fair price looks like.

Gas lines
Sealed refrigerant
240V
Permit work
Stop line reached
“This one isn't yours to do. Here's what to say so you don't get sold a new machine.”
Being the only source that says stop is exactly why people trust the times it says go ahead.

Why Repair Logic

The advice has no inventory behind it.

The only home-repair diagnostic that carries no parts inventory — so it is free to tell you the repair is not worth doing, or to put the screwdriver down and call a pro.

  • Instead of YouTube

    An ordered path matched to your model, not four videos that guess at which check comes first.

  • Instead of a parts catalogue

    RepairClinic and Sears PartsDirect are owned by the part they sell. We carry none, so we can say a machine is not worth fixing.

  • Instead of paid expert chat

    You see the ranked causes and the verdict before paying — not a chat that quietly becomes a monthly bill.

  • Instead of a chatbot paragraph

    We ask for the model plate, rank by likelihood, price the part, and refuse to guess on gas and refrigerant.

  • Instead of a $125 call-out

    A diagnosis and forty minutes of your own first. When it is not the filter, you reach the technician better armed.
