Do-it-yourself Dishwasher Repair – How to Fix Simple Dishwasher Problems

The dishwasher is an electromechanical device for automatic washing of dishes. This kitchen appliance is a dream of every person who does not have one, and an indispensable “helper” for the happy owners. Buying a dishwasher, each member of the family hopes that now they will never wash dishes by hand.  Unfortunately, such a possibility is not excluded, because the dishwasher, as well as any other technique, can break down.

What are the main faults of the dishwasher? What preventive measures to take to ensure that an indispensable household appliance served as long as possible without damage?

Dishwasher repair – the most common problems

Spray arm does not rotate

The machine needs a spray arm that should rotate – this should be determined by the pressure of the running water that must pass through it. If the pressure is too low, the arm will not move. The culprit may be a worn gasket letting the water go and thus lowering the water pressure in the arm. Checking and replacing the gasket with a new one should solve the problem.

Another cause may be too low water pressure.

So, it is worth checking the water pump, all hoses and valves – the pressure should be at least minimum for the arm to rotate. Or maybe something… has blocked the arm? It’s a fairly trivial problem, but sometimes food really likes to get into all sorts of nooks and crannies of the dishwasher. That’s why it’s a good idea to take a look inside and see if something is holding the arm – rather than calling a dishwasher service in a panic.

Dishwasher rinses too little – dishwasher repair

You take dishes out of the dishwasher and they’re full of… soap scum. What to do in such a situation? Do-it-yourself dishwasher repair should begin with determining whether the wash pump is even delivering water. It should help to clean it or replace the defective element if the previous action proves ineffective. Also check if the washer is working – it is responsible for distributing water around the chamber. If the holes of the washer are stained or the pressure in it is too low, you know that the dishes will not rinse out very well. Therefore, clean or replace this component.

 Also focus on the siphon, solenoid valve, filters and water jacket – of course, if the cause is not the above problems. Clean the components and see if its dirt blocking the rinse water. The dishwasher is constantly in contact with water, so limescale can build up on it.

 Dishwasher dries dishes poorly

Find out if the household appliance is heating up. Lack of heat generation is a result of ineffective drying – the heater is responsible for drying dishes. Maybe it burnt out? Then you need to replace it yourself or call a dishwasher service. Another reason may be a faulty fan. It is responsible for distributing warm air around the appliance chamber. If there is a defect in the motor or the fan blades are chipped, it will be necessary to replace this element.

A trivial, yet often occurring problem is… not adding rinse aid to the dishwasher. If you want to improve the quality of drying, the liquid must always be in the device! The last cause can be the suspension of the solenoid valve, when it drains water from the water jacket of the dishwasher and it goes directly into its chamber. Dishwasher repair will then prove to be a necessary solution – because the water goes into the chamber at the wrong time, hence the problem of under-dried dishes.

Your dishwasher is leaking water!

Your dishwasher will need to be repaired if its propellers are clogged – they are the most important parts of the dishwasher that rinse dishes. So, check if there are any food residues in them and if they are blocking the propellers. Take a closer look, because it may turn out that the elements are simply… leaky. Then you will have to replace the propellers or fill them. Or maybe the hydrostat is damaged? Check it and clean it thoroughly. The last cause of water spilling from the home appliance may be a rusty water pump.

The dishwasher won’t start a cycle

Check the control module – if everything is fine, simply reset the machine. Also check if the water drain is clogged – as the dishwasher’s plumbing must be unobstructed if water is to be supplied to it. No water means the appliance won’t start working. Also check the filter and water pump – maybe there is too much water and the dishwasher won’t start?
