Dishwashers are fantastic modern appliances that can save you hundreds of hours of washing up over the course of the year. Unfortunately, dishwashers don’t come cheap, so once you’ve made the decision to include one in your kitchen, you’ll want to maintain it for as long as possible.
Dishwasher repairs will be necessary sooner or later, so it pays to get familiar with the common things that can go wrong.
Problem 1: Water dripping from a stuck float switch
If you notice water dripping from the bottom of your dishwasher, it’s usually due to a stuck float switch. The float switch is a small cylinder inside your dishwasher that floats up when water reaches a certain level, turning off the water inlet. When it’s stuck, it doesn’t do this, so the dishwasher keeps filling, eventually causing it to leak.
Soap residue inside the switch is usually the culprit.
The solution? Remove the white cylindrical cup, thoroughly clean away the residue, and then replace it. The cup will be free to move again, and the water drip should cease.
Problem 2: Air gap shooting water out
This indicates that the rubbish disposal drain line from the dishwasher has become clogged. Your dishwasher frequently removes food and gunk from your dishes and drains it away. Sometimes this material can accumulate in the drain line and clog it.
The solution? You will need to clean the line out, or if it’s packed full of gunk, look to replace it. Significantly clogged drain lines can usually be cleaned by connecting them to a hosepipe and blasting water through them.
Problem 3: Broken soap dispenser
If the soap dispenser isn’t opening properly or is stuck open, it’s usually an issue with the spring inside.
The solution? You may need toreset the spring latch. To do this, take the dispenser off and slot it back in carefully, making sure that the spring contacts are in the correct spot. The dispenser should now spring closed correctly.
Problem 4: Dishwasher not filling with water
If your dishwasher refuses to allow water in, the problem likely lies with the water inlet valve. Usually when it’s come to the point that it won’t fill at all, it means that the water inlet valve will need to be replaced.
The solution? You’ll need to buy a replacement that fits your machine, and you’ll need to turn off the water and electricity to your dishwasher. The valve is located under the toe kick plate at the bottom of the dishwasher.
Remove the plate, and when you find the valve, carefully disconnect it with screwdriver and pliers. You’ll also need to transfer the fitting from the old one to the new one before you replace it. Once that’s done though, your dishwasher should fill fully and swiftly again.
