Appliance repair safety basics

1. Cut the power

Unplug the appliance before any step that goes beyond pressing buttons. Dishwashers are often hardwired; for those, switch off the dishwasher’s breaker at your electrical panel. Whirlpool gives exactly this advice for its dishwashers.

When you plug back in, use a wall outlet directly. Samsung and LG both advise against extension cords and power strips for washers.

2. Turn off the water

Before you touch a supply hose or connection, close the valve. Washers have two valves behind them, for hot and cold. Dishwashers usually have one under the kitchen sink.

3. Let it cool

Water from a hot or sanitize cycle can scald. Samsung suggests waiting about an hour after a hot cycle before cleaning a washer’s pump filter. In a dishwasher, the heating element at the bottom of the tub stays hot for a while after a cycle.

4. Expect water

Opening a front-load washer’s pump filter, or disconnecting a drain hose, will release water. Lay old towels down and have a shallow tray or baking dish ready before you start, and empty it as often as needed.

5. Never force a door or lid

Washers lock the door during a cycle for good reason. If it won’t open, the cycle may not be finished or water may still be inside. Samsung notes the lock releases once the cycle ends and the water has drained, and that a top-load washer can take up to 5 minutes to unlock after a power cut. Don’t pry it open or bypass the lock.

6. Moving the appliance

Washers are heavy and dishwashers are fixed to the counter. Get help to pull a washer out, protect the floor, and take care not to stretch or crush the hoses and power cord behind it.

When to stop

At that point a technician is the safe choice. Our guides end with a summary you can copy and send them, so the visit starts with what you’ve already checked.
