Field evidence

Start With the Appliance, Symptom or Code You Actually See

This library turns anonymized field reports into readable diagnostic paths. It preserves what was observed, what was tested, what failed and what was actually confirmed.

Three faster ways to find a useful case

Browse by symptom when you only know what the appliance is doing, by error code when the display gives you a lead, or by brand and model when model-specific behavior matters.

The same symptom can have a different cause. Each case is a comparison point, not a promise that the same part will fix another appliance.

What a strong field case looks like

Confirmed examples

Follow the evidence, not a parts list

Sub-Zero short after fan work: reversed wires confirmed LG washer vibration: deposits on the spider confirmed GE gas dryer short cycling: airflow condition confirmed
Safety boundary: the library helps readers understand diagnostic reasoning. It does not provide homeowner procedures for live voltage, gas, refrigerant or energized moving equipment. Use the safety guide before acting on a case.
Parts changed, problem stayed

A replacement that did not solve the fault

Includes a recorded replacement that did not help GE Café Dispenser Flap Opens When the Lower Door Closes A GE Café dispenser flap opens when a lower door closes. Failed boards and dispenser parts gave way to a confirmed embedded door-switch fault.
Unexpected turn

A repair that did not follow the obvious path

An unusual turn supported by the case record Thermador PDR366ZS Simmer Recall After Control and Igniter A Thermador PDR366ZS simmer problem returned after a control and igniter repair. The knob switch and potentiometer path became the next branch.

Recently published cases

Whirlpool F03 E01 with Drain Running Forever A Whirlpool ran its drain forever, flashed the lock lamp and showed F03/E01 after a level-sensor connection changed. The signal path came first. Maytag MVW7230HW0 Quick Wash Stuck at 17 Minutes A Maytag MVW7230HW0 kept operating while Quick Wash remained at 17 minutes. The case separates a stalled countdown from a simple no-spin fault. Maytag F1E2 After Drain Worked and Programs Stopped A Maytag drained correctly, then programs stopped after pause and F1E2 appeared. The case separates standing-water door lock from motor control.
