Buy a Good Multimeter
How do you know if a problem is in the appliances's wiring? You test it! And for that, you need the right tool. Purchase a multimeter that allows you to measure voltage and other important signals that show you which wires or electrical components aren't working. If you want to become a master of home appliance repair, you need a multimeter and always be sure to take proper safety precautions.

Check Ignition Processes
If you have gas-powered appliances, they depend on an ignition process to get started. And some have electric starters and some have pilot lights, but either way this is a common source of problems in otherwise highly durable appliances. Check your ignition process and make sure the pilot light is on, the starters are properly aligned, and that nothing has been blocked with soot.

Know Where Your Hoses Are
Your dishwasher, washing machine and many other appliances depend on hoses to move water around. And if a leak or kink occurs, you need to check these hoses and surrounding valves to locate the part that needs to be replaced and re-sealed. Hoses tend to wear out before other components, so pay attention to the condition of these hoses when doing home appliance repair.
