Home Appliance Repair
Overview
• Diagnosing a single common fault (e.g. washer not draining, fridge not cooling) and replacing the defective part.
• Skill level: 3 / 5 (confident home improver with basic electrical know‑how).
• Typical duration: 1–2 hours.
Safety First
Switch off and unplug the appliance; lock the consumer‑unit breaker if hard‑wired.
Turn off water or gas supplies feeding the unit.
Discharge stored energy—wait 5 minutes for capacitors to bleed down.
Wear cut‑resistant gloves; appliance edges and sheet‑metal panels are sharp.
Use safety glasses when working under the machine—rust flakes can fall.
Tools & Materials
Item | Purpose |
Multimeter (AC/DC & continuity) | Confirm power is isolated and test fuses, heaters, pumps |
Screwdriver set (Pozi, Torx, Hex) | Remove appliance panels and PCB covers |
Adjustable spanner / slip‑joint pliers | Undo hose unions and compression fittings |
Needle‑nose pliers | Pull crimp connectors from motor terminals |
Replacement part (pump, belt, thermostat, seal) | Fix the identified fault |
Cable ties / insulation tape | Secure wiring looms after refit |
Towels & shallow tray | Catch residual water when hoses disconnect |
Work light or head‑lamp | Illuminate inside dark appliance cavities |
Step‑by‑Step
1. Isolate and Inspect
Unplug or switch off the fused spur; check dead with multimeter. Slide the appliance out and look for leaks, burn marks or loose wiring.
Why: Ensures personal safety and confirms obvious issues.
2. Retrieve Error Codes
Enter service mode (consult manual) or note LED flash sequences. Why: Narrows the fault quickly.
Pro‑tip: Photograph the code to reference while parts shopping.
3. Access the Fault Area
Remove rear or bottom panel using the correct driver bit; keep screws in a cup. Why: Provides working space around the suspect component.
4. Test Suspect Components
Measure resistance of pumps, heaters or sensors; compare with spec sheet. Check belts for slack and motors for seized bearings. Why: Confirms what actually failed.
5. Replace the Component
Disconnect wiring, slacken clamps or bolts and swap in the new part. Align gaskets or O‑rings precisely to prevent future leaks. Why: Restores full function.
Pro‑tip: Photograph wiring before removal so re‑assembly is fool‑proof.
6. Re‑assemble and Secure
Route cables away from moving parts; tie back with zip‑ties. Re‑fit all panels, ensuring no earth straps are trapped.
Why: Returns appliance to safe factory condition.
7. Test Cycle and Leak‑Check
Restore power and water/gas, run a short cycle or cooling test. Observe for vibration, leaks or error codes; tighten connections if needed. Why: Verifies the repair under real conditions.
Completion Checks
Appliance runs a full programme without error or abnormal noise.
No water, gas or refrigerant leaks present.
Panels sit flush, screws tight and earthing intact.
Replaced component remains cool (where applicable) after 10 minutes’ operation.
Work area clean; tools and old parts disposed of responsibly.
When to call a pro instead
If the fault involves sealed refrigeration circuits, mains‑voltage PCB diagnostics, strong burning smells, repeated tripping of the breaker, or removal of integrated cabinetry, engage a qualified appliance engineer. They hold the test equipment, spares access and insurance needed for complex electrical and gas repairs.
