Dishwasher Repair and Care (Troubleshooting and fixing problems)

Learn about some of the most common problem related with dishwashers and how to repair and fix them.

You should understand that a dishwasher, like any other home and kitchen appliance, is just a machine and should be handled with care while operating. Because a dishwasher is a machine, it will surely need some or the other kind of repairing at some or the other point of time. There is nothing to worry about if something goes wrong with your dishwasher or if your dishwasher stops working properly. There are several things you can do to get your dishwasher work properly.

Following are some of points to keep in mind before you start working to solve common dishwasher problems:

1) Always switch off your dishwasher power supply before forking on it.

2) Always turn off all water supplies to the dishwasher.

3) After a dishwasher has done washing dishes and utensils, it need some time to cool down. Never work inside the dishwasher immediately after a wash cycle. Some of the parts inside the dishwasher, like the electric dryer element, may still be hot.

Now that you have taken all the precautionary safety steps, you are ready to fix and solve your dishwasher problem.

Let us now learn about some of the common problems with dishwashers and how to fix and solve these problems.

If you dishwasher is making too much noise, it is very much possible that some part or parts is faulty. It may also happen because of dishes are not loaded properly. Check the manual for proper loading methods.

If you have just run your dishwasher, allow it to cool and then look in the openings around the pump at the bottom of the dishwasher's interior to make sure that no hard material such as bones, fruit pits, or silverware are stuck in them.

Make sure your dishwasher is sitting level. Adjust the feet beneath the unit by screwing them up or down as required. Make sure all the lock nuts are tight.

If you are still not able to solve the problem, call a repairperson.

If your dishwasher runs but doesn’t fill, either something is wrong with its water supply system or it is draining water too soon. Do following to solve this problem:

1) Make sure the water is turned on. Check the hot water supply stop valve. Open it by turning it counterclockwise. If there is no reason this would have been turned off since the last time the dishwasher worked, move on to the next step.

2) Turn off the power to the dishwasher. Do this before all repair works.

3) When the dishwasher is cool, look for the float inside the dishwasher which a small plastic dome or cylinder mounted inside at the tub’s base, near the front. When you move most types of floats up and down, you can hear them click because they trip a lever as they are spring-loaded. Lift out the float mechanism, and clean around the float tube. Rinse off the float, replace it in the tube, and make sure it moves up and down freely.

4) Shut off the hot water valve to the appliance and locate the water intake valve, behind the dishwasher’s bottom front panel. Disassemble the valve to reveal the screen, clean debris from the screen, and reassemble. If the screen doesn’t appear to be blocked, you may call a repairperson.

5) If you are still not able to repair and fix the problem, call a repairperson.

1) If there is water leakage around the base of your dishwasher, most probably you are using a detergent that is too much sudsing. Cut back on the amount of detergent you use, and see if this solves the problem.

2) Water that spills through the door vent of the dishwasher is normally caused by not loading dishes properly. Leaks from the door itself may be caused by a faulty door gasket or door tightness adjustment.

3) Also make sure the dishwasher is sitting level.

4) If there is water under the dishwasher, it may be originating from a leaky hose or loose hose connection. Remove the lower front panel, and check the hoses. There could be some defect in the pump seal. You cannot replace this pump seal yourself. Call for an appliance repairperson.

5) A very old dishwasher may corrode at the bottom leading to water leakage. If this is the case with your dishwasher, it's time to buy a new one.

There could be several caused for this. If there is excessive water, it means the pump is not pumping water out properly or the drain hose isn't carrying it to the drain pipe. If dirty water spews from the air gap, the drain line is kinked or clogged. Do following that may solve and fix your problem:

1) Remove the cover from the air gap at the top of the sink and clean it using some wire. You may also check the entire length of the drain hose for kinks and blockages. There could be some blockage.

2) Cut off power supply and remove the strainer, located under the bottom spray arm at the base of the cabinet. Unscrew the hubcap, lift the spray arm off, and remove any clips that hold the strainer to get it out. Scrub and clean with a brush, and replace it.

3) Check if the sink trap or house drain line is clogged.

4) If the dishwasher still doesn't drain properly, it is possible that the drain hose is clogged or the drain valve needs to be replaced. Call a repairperson for this.
