Hansa dishwasher not working? Do not worry, we will help you fix the problem. In this technique, anything breaks, so the PMM self-diagnosis system displays a malfunction code on the display. The code indicates the cause of the breakdown, but the symptoms of the problem should also be considered.
Learn how to repair your Hansa dishwasher yourself.
The reasons for the breakdown of the Hansa dishwasher
Consider the main reasons for the malfunction of the Hans dishwasher. To make it easier to understand, pay attention to the "behavior" of the machine.
- PMM does not start washing. A breakdown is expressed in the fact that after the intake and heating of the water, the washing cycle does not start. Probably, the drain filter or nozzles on the beam that spray water are clogged. In this case, the machine does very poorly washing dishes if the cycle starts.
Least of all there is a breakdown of the circulation pump, which pumps water into the dishwasher. - The equipment does not collect water in the tank. A simple malfunction is a blockage in the system. It is easy to fix on your own. A more complex failure is the failure of the filler valve; repair is indispensable.
- The dishwasher does not heat water, dishes are poorly washed. So, there are problems with the heater, which is responsible for heating the water. Another sign of failure is that the machine is shocking.
The wiring is checked, the heater is called by a multimeter. Defective item replaced. - The machine collects and drains water or draws it more than normal. The problem must be sought in the pressure switch. The device controls the amount of water in the tank. If it fails, a complete replacement is needed.
- PMM does not drain water after washing. Then you need to check the drain path: filter, pump, drain hose.
- Is there a water leak? Then all connections, the tank are inspected, the seals are checked.
Now you know why the Hansa dishwasher does not work as usual. It happens that the dishwasher does not turn on at all. Then check the voltage in the outlet by connecting another device to it, inspect the power cord for damage.
If everything is normal, the equipment could suffer from a voltage drop. Diagnose the control board fuses before turning on the PMM.
How to repair a dishwasher with your own hands
If, after connecting to the network, the PMM displays an error code on the display, try to reboot. How to reset the system and restart the dishwasher:
- disconnect the equipment from power for 15-20 minutes;
- reconnect to the network.
If, after a reboot, the PMM started without an error code, then there was a system failure. You can continue to work.
Repair needed? Before disassembling the machine, look at the diagram of its device.
Solving problems with the filling system
No water entering the tank? Consider how to fix the situation.
Eliminate the blockage:
- Turn off the water supply in the machine and unplug it.
- Disconnect the inlet hose from the body.
- Check it for a blockage.
- Remove the filter screen. Rinse it under the tap. If it is very dirty, leave the filter to soak in a solution of citric acid.
- Diagnose the filler valve.
- Ring the electric coils with a multimeter.
If there is a malfunction, install a new valve. How to do it:
- Empty the machine tank, remove the baskets and remove the sprayer.
- Pull out the filter and remove water with a sponge.
- Turn the machine over to gain access to the bottom.
- Remove the front panel below by unscrewing the mounting screws.
- Disconnect the valve wiring and unscrew the mounting bolt.
- Install a new part.
Checking the circulation pump
The circulation pump in the dishwasher serves to pump water. Thanks to the pump, water flows into the rocker arms and washing the dishes begins. If you notice that the engine (pump) is noisy, buzzing and does not spray water, then it needs a replacement.
DIY repair:
- Access the bottom of the machine as described above.
- Unscrew the bottom panel if it is in your model.
- First you need to disconnect the drain pump.
- Unscrew the screw of its fastening.
- Turn the pump clockwise.
- Disconnect the engine wiring.
- On the inside, the engine is secured with a clamp. Press it to disconnect the engine.
- Using an adjustable wrench, remove the clamps from the hoses that are attached to the pump motor.
- All you need to disconnect the three hoses.
- Remove the spring clip from the old pump and install on the new one.
- Reassemble in the reverse order.
Troubleshooting the drain system
When the water does not leave the machine, the dishes are washed poorly, check the system for clogging:
- Pull out the lower beam by pulling it towards you.
- Unscrew the upper beam and remove.
- Inspect the spray nozzles for clogging.
- Clean the holes with a toothpick.
At the bottom of the tank is a drain filter. Pull it and the metal mesh next.
Eliminate leftover food and debris. Wear gloves and check the impeller of the pump. Blocking by glass fragments is possible.
Replacing the drain pump is easy. See the description of replacing the circulation pump.
Level Sensor Replacement
A level sensor or pressure switch in the dishwasher monitors the amount of water in the tank. Its electronic or mechanical parts may break, the tube may become clogged. Therefore, before replacing, check the device for serviceability, clean the tube from clogging.
There is a pressure switch at the bottom of the machine. The device looks like a box from which the tube goes. Remove the two mounting screws, disconnect the clamp and tube. You can check the part by blowing it into the tube. If you hear clicks, then the sensor is working. The electronic part is checked with a multimeter.
Diagnostics of the heating element
A flow-through heater is used to heat water when washing dishes. If heating does not occur, you need to check the wiring and connectors of the heater; it is located under the bottom of the Hansa PMM. In case of burning, its parts need an urgent replacement. The heater contacts are dialed with a multimeter.
How to install a new part:
- Flowing heater is connected to the pump.
- Unscrew the pump mount, turn clockwise, remove from the seat.
- Remove the rubber seal from the heater.
- Remove all pipes and connectors that are attached to the heater.
Install in the reverse order.
Search for leaks
To eliminate the leak, you need to establish the cause of its occurrence:
- Inspect the dishwasher tank.
- Check the tightness of the door, the quality of its seals. In case of violation of the integrity of the elastic easily changes to a new one.
- Damage to the seal on the drain pump also leads to leakage. It is necessary to change the seal or the entire pump.
- Check the joints of the inlet and drain hoses. When leaking, the connections are tightened. If the hose itself is leaking, a replacement must be made.
In conclusion, we show you how to use the dishwasher.
How to avoid PMM breakdown
Following the instructions will allow your technique to last longer. Follow simple rules:
- Clean dishes thoroughly from food debris.
- Carry out the correct installation of the equipment. Often the reason for the lack of water is an incorrect connection.
- Install a circuit breaker for expensive appliances. This applies to Hans dishwashers and washing machines. The machine turns off the power when overloaded in the network.
- Use a quality detergent.
- Check door closure for tightness.
- Load the dishes following the instructions.
Breakage is easier to prevent than to repair. Take care of your technique, and she will take care of your dishes.
