Dishwasher Repair Troubleshooting Tips:

Won't turn on

Make sure your dishwasher is properly connected to the power source. If it isn't the power, the motor, door latch switch or control timer/panel may be bad.

You might also need to check the wires inside the junction box for corrosion, breaks or loose connections.  Also check the interior of the junction box for any burn or "arc" marks. If this is the case, call a qualified appliance repair technician.

Doesn't clean dishes

Operator error? Never overfill your dishwasher, as this can obstruct the function of the spray tower or arms.

Other possible problems include bad detergent (cleaners that contain phosphates leave a white film on dishes) or low water temperature. Ideal dishwasher water temperature is between 130 and 150 degrees Fahrenheit.

Doesn't rinse/fill with water

Check to make sure the float assembly (inside the dishwasher near the door on the floor of the dishwasher) moves freely up and down. If not, the float switch might be defective or stuck. Other problems include defective inlet valves or water supply problems.

Note: Remember to turn off the water before working on the water line.

Doesn't drain

Check to make sure the strainer is not clogged with food or debris, such as bones, fruit or silverware. If the strainer is all clear, check to make sure the drain hose is not blocked, bent or kinked.  On the other hand, your dishwasher might not be the problem. Check the garbage disposer for a clogged drain line.

Leaks

Leaks are often caused by hose problems. First, check the drainage hose for cracks or loose connectors. Leaks can also be caused by loose or bad heating element gaskets. To replace bad gaskets, simply unscrew the heating element and unlock it from its holders.

Won't dry dishes

Faulty vents or burnt out fan motors or heating elements are likely the cause. Access and inspect the drying fan by removing the lower panel located beneath the door.

Note: Remember to shut off the water supply and unplug the power when attempting to replace a heating element.

Makes strange noises

Strange thumping, chattering or knocking noises can be caused by many things, including too many dishes, faulty parts, debris or an appliance that is not sitting level. The inlet valve might also be clogged or need to be replaced.

Refrigerator Repair Troubleshooting Tips:

Make strange sounds/noises

Some level of hissing and popping is normal for frost-free refrigerator models. Locate the sound (i.e., front, back, inside, bottom). Check for faulty evaporator, condenser and compressor fans and mounts-replace if necessary.

Noises coming from inside the fresh food compartment indicate a faulty defrost timer.

Stay warm/Not get cold enough

(Ideal temperature settings: Refrigerators: 36 to 40 degrees Fahrenheit/ Freezers: 0 to 8 degrees Fahrenheit)

Try testing the temperature setting first. Additional troubleshooting tips: Assure there is sufficient room for air flow (both inside and outside the unit); check door seals, evaporator and condenser fans; check for a blocked drain tube or a coolant leak. In the case of coolant leaks, call an appliance repair expert.  

Run all the time

Continuously running for more than a 24-hour period may indicate a problem. Try cleaning the condenser coils (underneath the unit), or checking the door seals or testing the door switch. There might also be a coolant leak. Note that it is common for units to run (in an attempt to cool down) after temperature adjustments, after being loaded or if located in a humid environment.

Leak water inside unit

Check for a blocked drain tube. Unplug the unit and locate the drain plug near the back or bottom of the main compartment.

Leak water on floor

Check the drain pan. If you have an icemaker, check for a leak in the water supply hose. Also, if the refrigerator is completely level or tipped slightly forward, the water may not be able to drain properly.

Apart from leaks, consider cleaning the drain pan periodically to prevent mold.

Have ice buildup (freezer)

Check the door gasket for leaks. Place a flashlight in the freezer, pointing the beam towards the door. If light is still visible when the door is closed, the gasket should be replaced. Purchase gaskets from the manufacturer or a large-appliance retailer.
