The dishwasher is part of our daily life. We expect her to wash our dishes. There are many problems that can occur with a dishwasher. Understanding the various signs can help you identify the cause of a dishwasher breakdown.
Steps
Method 1 of 8: The Dishwasher Doesn't Work at All
Step 1. Check the fuses and circuit breaker to make sure none of them have blown or broken
You should also check to see if the dishwasher plug is firmly plugged into the outlet.
Step 2. Check the plug wires for breaks or other damage
If you find any damage, then the electrical cord must be replaced.
Step 3. If you have followed the above steps and the dishwasher is still not working, then the cause of the breakdown is a malfunction of the mechanical parts
In this case, check the door latch to make sure it is working properly.
Step 4. Check the door and switches for continuity with a multimeter
You should also check the timer, motor and motor relay inside the dishwasher.
Method 2 of 8: The motor hums, but the dishwasher won't turn on
Step 1. Inspect the motor and pump for blockages and other debris
If necessary, clear the blockage. Also inspect the drive belt for wear and other damage.
- If there is no blockage or any damage, check the motor and relay for continuity.

Method 3 of 8: Dishwasher Will Not Fill or Drain Water When Filling
Step 1. Check that the water supply to the appliance is on and that there is no leakage between the water supply and the dishwasher
Step 2. Make sure there are no kinks in the water supply hose that prevent the dishwasher from filling with water
Inspect the door latch, float, inlet and drain valves. Inspect the flap flaps for blockages.
Step 3. Check the switches for the door and float for continuity
You should do the same for the intake valve if visual inspection shows nothing.
Step 4. Make sure the drain valve is working
The drain valve consists of two parts, a rocker arm and a solenoid.
- Grab onto the rocker arm and try to move it up and down. It should move freely. If it goes tight, make sure the springs are present and not damaged.
- If the rocker arm is intact but does not move as it should, then you will need to replace the solenoid. Remove the connecting wires with long nose pliers and mark them. Unscrew all screws with a screwdriver and replace the faulty solenoid.
Method 4 of 8: Water Does Not Drain
Step 1. Inspect the hose for kinks
You can also replace any other possible damage. Also check the motor and pump for blockages.
Step 2. Inspect the drive belt and hoses for damage or breaks
Check the resistance of the drain valve and the conductivity of the timer.
Method 5 of 8: Leaking water or soap
Step 1. Check the soap used
The detergent must be specially formulated for dishwashers. Make sure the dishwasher does not overflow with water.
Step 2. Inspect the door latch, hinges and gaskets
Also inspect the insulation around the bucket, float, heater and diffuser.
Step 3. Inspect the drain hoses, inlet valve, pump, and centrifugal pumps for damage
Method 6 of 8: Noisy dishwasher
Step 1. Inspect the spray nozzles, inlet filters, and drain hole for damage or blockage
The intake valve is also worth checking.
Step 2. Inspect the motor and dishwasher mountings
It is also recommended to inspect the fan motor and fan blades for any damage.
Method 7 of 8: The wash cycle does not complete or takes too long
Step 1. Check timer, thermostat and heater for conductivity
Method 8 of 8: Keeping Dishes Dirty
Step 1. Check water level, pressure and temperature
Clean the particle filter and water inlet filter.
Step 2. Make sure the detergent dispenser, nozzles and various valves are working
Make sure there are no blockages in valves and hoses.
Step 3. Check that the inlet and drain valves have correct conductivity and resistance
You should also inspect the selector switch, timer and heater for correct conductivity. The last one to inspect the mechanism of the bimetallic terminal
Advice
- You will need a screwdriver and pliers to remove the panels and connectors. You will also need a conductivity tester and a multimeter.
- Broken and defective parts can cause various problems. Checking multiple parts of a dishwasher to check for one or two faults is not uncommon. This article will help you narrow down possible faults.
Warnings
- Wear shoes with rubber soles and do not work in damp areas. It is also recommended to use insulated tools when working with electrical devices. The right shoes and tools will help you avoid electric shock.
- Always turn off the power to the device before checking the components. Call a professional if you are unsure how to perform component checks.
