Error F54 on Gorenje dishwasher

Error F54 on Gorenje dishwasher With sensitive household appliances, a lot can go wrong, so you shouldn’t be surprised that the manufacturer has provided dozens of fault codes for all occasions. Error F54 is often encountered by housewives, so many may have had time to learn why it occurs. The code appears on the display due to the fact that the “home assistant” is overfilled with water during the working cycle, which is why it cannot continue working. Let's look at why this could happen and what can be done about it.

List of possible problems

The strange error F54 in the Gorenje dishwasher always occurs due to problems with the drainage. This can happen due to an ordinary blockage, or it can occur due to a breakdown of one of the key components of the PMM. To understand what to do, you must first examine each of the possible causes of the malfunction.

The user accidentally kinked the drain hose, which is why the water physically cannot go down the drain. In this case, it is enough to simply straighten the sleeve and try to start the working cycle again. This happens very often, so you shouldn’t rule out this option.
The coarse filter is completely clogged, so the waste liquid simply gets stuck. To prevent this from happening, you should always first clean the dishes from food debris, seeds, tea bags, napkins, toothpicks and other debris. This will eliminate the risk of filter clogging in the future so that water always flows freely from the tank.
The drain area is clogged. This also happens due to food debris and other contaminants that could pass through the garbage filter, but block the pipe, drain hose or pump.
The pump has failed.
The water level sensor is broken.
The control board of the Gorenje dishwasher is damaged.

Experts always recommend starting the inspection with the most basic causes and gradually moving on to serious damage. This will prevent you from wasting time if the error code was caused by something simple that does not require complex repairs or replacement.

We clean the machine, change the pump

If error F54 appears on the display of your machine, then first of all the equipment must be disconnected from all communications. Next, examine your equipment for clogs, starting with the drain hose, which is the most commonly clogged drain. To do this, you need to disconnect the hose from the sewer, lower it into a container or bathtub and check if the water comes out. If it does, then the siphon or sewer is clogged, and if the waste liquid does not come out, then the clog should be looked for in household appliances. Let's start by cleaning the filters.

Open the washing machine door.
Remove all dish baskets.
Remove the cover of the debris filter located at the bottom of the wash chamber.
Pull out the filter glass, and then the filter mesh.
Rinse the filter elements under a powerful stream of hot water.

If contaminants have already become embedded in the parts, an old toothbrush will help clean them, as well as a citric acid solution in which you can leave the filters for several hours.

Open the pump cover and carefully test with your finger whether the impeller rotates, which could also contain debris, as well as broken dishes if they were broken during washing.

Next, you need to return all the elements to their seats and test the operation of the equipment during an idle start. If all the manipulations done did not help, then you will have to partially disassemble the equipment to get to the internal components of the Gorenje dishwasher. Let's start with the pump.

Drain all the used liquid from the PMM, which can be done manually by scooping the water out of the tank, or by tilting the “assistant” forward to pour out all the water.
Remove the drain filter.
Turn the household appliance on its back to remove the tray secured with self-tapping screws.

Under no circumstances pull the pan with force, since on some Gorenje PMM models an Aquastop sensor is attached to the pan, which must first be removed by disconnecting all wiring.

Disconnect the sensor, if present.
Remove the tray.
Unscrew the pump, removing all hoses from it.
Examine the impeller to see if it rotates without problems. If not, you will have to buy a new part and install it in place of the failed one.
Measure the resistance of the element by connecting the probes of a simple multimeter to it. Normal resistance will be around 200 ohms.
Additionally, you can check whether voltage is coming to the pump from the control module of the Gorenje dishwasher.

If the pump really fails, then it can only be replaced, preferably with an original spare part, so that the performance of the machine does not decrease due to a low-quality element.

The level sensor or the PMM “brain” is to blame

If, due to error F54, waste liquid remains in the sump of your Gorenje device, then this could also happen due to the pressure switch. The reason is that if there is a problem in the pressure tank or in the sensor tube itself, the current water level data may be transmitted with errors. In this case, the pressure switch, even with a full pan, will not send a drain command to the control module of the equipment, which will not start the pump. In this case, you will have to change the water level sensor. control module PMM Gorenje

Finally, if the pressure switch is working properly, then all that remains is to look for the problem in the dishwasher control board, because it is this board that will not transmit the signal to drain the water. This can happen due to a one-time failure, an error in the operating system, or due to simple wear and tear of the node. The control module is considered the “brain” of the entire system, so its repair or replacement should be carried out by a professional who will not accidentally damage the equipment further.

It is not enough to simply reset error F54 - be sure to conduct a test work cycle after getting the “home assistant” working. This will allow you to understand whether the problem has been solved or whether specialist help is required.
