Daewoo Error Codes and Dishwasher Fault Repair

None of the equipment is insured against malfunctions during operation. DAEWOO dishwasher errors are designed to help the user determine the cause of the breakdown. Even if you have lost the instructions for deciphering the codes, it does not matter. In the article you will find not only the meaning of each error, but also a detailed analysis of the problem.

How are Daewoo fault codes deciphered?

The error appears on the PMM screen as an alphanumeric value. It’s good that the machine did not just stop working, but issued a fault code. Having learned the meaning of the symbols, you can begin to fix the breakdown. Let’s list them:

Symbols on the PMM screen

• E1 – the code means that the dishwasher door is not completely closed. Perhaps the dishes are interfering or the door is skewed due to improper installation.
• E2 – the water intake valve is faulty. There was a problem with the water supply. Causes include clogged or broken valves.
• E3 – water does not leave the bunker well, which means a blockage or malfunction of the pump, filter, improper drain connection.
• E4 – the temperature sensor does not work correctly. Probably, the contacts have moved away from the sensor or it needs to be replaced.
• E5 – bay / leak. Contact the service center.
• E6 – leak in the dishwasher. How to fix it yourself? Inspect the equipment and find the place of leakage, eliminate the cause of the problem.
• E7 – problems with heating. Check heating element.

Sometimes a reboot helps to get rid of the code on the scoreboard. The system may also fail, causing the PMM to mistakenly issue breakdown codes. Here’s how to restart the PMM “Daewoo”:

• Unplug the dishwasher from the socket.
• Wait 10-15 minutes.
• Reconnect the PMM to the network.

The code reappeared on the screen. So it’s really broken. What problems are most common in DEU dishwashers? Consider the problems and their solutions.

Daewoo dishwasher troubleshooting

The technician does not always report a malfunction with a code on the scoreboard. Sometimes it is worth paying attention to other signs. Here are the most common problems faced by Daewoo users:

• PMM does not turn on. The dishes are loaded, the detergent is poured, but nothing happens when the button is pressed. The reason may be a power outage, malfunction of the plug and socket, lack of water supply.
• Dishes don’t wash well. The most common problem is improper placement of dishes. The remaining reasons are as follows: breakdown of the heating element or pump, blockage, blocking of the impeller, malfunction of the temperature sensor and electronic module.

Appliances remain dirty after washing

• No waste fluid drain. Why is the drainage system not working? In addition to a pump failure, the filter, hose could become clogged, and the pressure switch could break.
• Extraneous sounds during operation. If this is not the sound of dishes, then the pump, which operates on the last resource, may wear out.

Typical breakdowns considered. It would be nice to know how to eliminate them without calling the wizard.

Attention! If the machine is under warranty, do not try to fix the equipment yourself. It is better to contact the service center. They will provide free warranty repairs, but only in the case of a factory defect.

Now let’s take a look at individual breakdowns and options for their elimination.

PMM won’t turn on

What to do first:

• Reconnect the plug to the outlet, make sure there is electricity.
• Check if there is water in the faucet, if the inlet hose is kinked.
• Push down on the hopper door until you hear a click. If it is not blocked, the wash will not start.

If these steps do not solve the problem, then check the intake system. What to do:

• Shut off the water.
• Find the place where the intake hose connects to the PMM body.
• Unscrew it and find the inlet mesh filter.
• Take out the mesh and clean it of debris. Often sand, pieces of rust get out of the water supply.

Valve assembly with filter

• To make sure the valve is working, it is necessary to measure the resistance of the coils with a multimeter. Attach its probes to the coil.
• The part is working if the device shows from 500 to 1500 ohms.
• If the readings on the display do not change, then it is time to change the valve.

Element replacement

Important! Experts do not recommend cleaning the old valve due to the high risk of failure after repair.

Details of verification and replacement are shown in the video:

In rare cases, the cause may be a breakdown of the electronic module. Only the master can detect this problem.

Dirty dishes at the exit

It is important to put the dishes in the baskets according to the instructions. Leave a space between the plates so that the water flows normally and rinses off the dirt. Also check that powder is being picked up from the washing container.

Examine the sprayers. Perhaps their holes are clogged with pieces of food and the water pressure is insufficient to properly remove contaminants. Remove the sprinkler and clean with a toothpick.

A more serious reason for poor washing is a breakdown of the heating element or temperature sensor. The latter controls the heating of water, and when it heats up to the specified rate, a signal is received to turn off the heating element. The thermistor is assembled with a heater, so we will describe how to get to these elements:

• Turn off the water and electricity supply.
• Open the door and take out all the baskets.
• In the pallet, remove the atomizer by pulling it towards you.
• Pull out the drain filter with mesh.

Filter location

• Remove the pump cover, unscrew the mounting bolts.
• Turn the car so as to get to the bottom.
• If there is a cover on the bottom, remove it.

The bottom of the PMM

• The assembly with the heater comes with a pump, to remove it, turn it counterclockwise. So you can at the same time check the pump for blockage and serviceability.
• Disconnect the wires and the rubber clamp of the heating element.

This is what the heater looks like.

• Remove the pipe and take out the heating element.

Check all elements, faulty ones cannot be repaired, replacement is carried out. The video will help you understand the principle of disassembly:

No drain

Above we described how to get to the pump. Now consider other causes of the problem. The main one is clogging. Here’s how to deal with it:

• Open the machine door.
• Take out the baskets.
• There is a filter in the pan. Pull it out and the grid next.

Filter and impeller

• Rinse with running water. The grid is well cleaned with citric acid or soda.
• Avoid blockage of the pump impeller. To do this, remove the water from the hole with a sponge.
• Pull and remove the cover. Put on gloves, remove debris.
• Examine the drain hose. If it is not pinched, disconnect from the case and rinse with water pressure.

Hose disconnect

Water leak

See where the water comes from and how much. Small drips under the door may indicate condensation that runs off after drying. If large puddles are collected, then it is worth checking all hose connections, the tightness of the door and the integrity of the sealing rubber.

Leak due to excessive foaming

The seal can also lose its tightness due to the abundance of grease on the surface, so do not forget to wipe it after each wash.

This is how you can deal with problems on your own. The manual will help you follow the rules of operation. The main thing to remember:

• Load dishes correctly in the drawer.
• Clean dishes thoroughly to remove food debris.
• Use anti-scale products, this will help to avoid damage to parts.
• Use salt to soften the water, then the dishes will be better washed.
• After finishing work, leave the door open for a while to allow the condensation to evaporate.

No wonder any technique comes with instructions. If you follow the manufacturer’s recommendations, the risk of breakdowns will be reduced to a minimum. We hope our article will help restore the PMM.
