Whirlpool dishwasher - error codes

Whirlpool brand appliances, which is produced in America, has been helping to maintain cleanliness and order in homes around the world for more than half a century. Dishwashers (DMM) from this company are in particular demand. Their build quality is at the highest level. Despite this, sometimes users encounter problems and breakdowns. It is not always possible to decipher Whirlpool dishwasher error codes using the instructions. Find out everything about how to determine the nature of the problem and fix it yourself.

Dishwasher won't start

Any user can encounter this problem. Startup errors often occur due to improper operation, manufacturing defects, and wear of key parts. The code on the display will help you find the cause of the problem. Here are the most common ones.

• A breakdown of one of the pumps that drains water. Water remains in the working tank of the PMM. Arises from wear and tear of this equipment.
• Violation of the Whirlpool dishwasher operating instructions. This category includes errors such as exceeding the maximum permissible weight of loaded dishes, or breaking the seal during operation (the door was not fully closed).
• Formation of leaks in pipes and other elements of the PMM water supply system.
• Low quality of detergents and cleaning products used. Find out which household chemical brands your dishwasher manufacturer recommends.If you save on these products, then the inevitable repairs or purchase of new equipment will cost much more.
• Weak water pressure. This may be caused by installation errors or malfunctions of the water supply system in your home.
• There are problems with the power supply to the device. Damaged power cord, broken socket.
• Dishwasher wiring problems. This leads to a short circuit and failure of the heating element.
• Damage to the central control module. The most common cause of this type of malfunction is power surges.
• The filter is clogged with food debris. Before washing dishes in a PMM, remove uneaten food from its surface. Check the filter for contamination at least once every six months.

Error codes

IN displaying the error code that occurs Having a display on the dishwasher helps. But among the rich assortment of Whirlpool there are models that are not equipped with a display. Although all error messages are standardized, there are quite a few different options for displaying them. The code can be displayed on the display using numbers and letters, indicated by flashing or lighting of indicators on the front panel.

Whirlpool error codes are divided into two large subgroups:

• type E;
• type F.

"E" error codes

This type of error appears on the display will be output as E <digit>. On devices equipped only with LED indicators, the code will be displayed using sequential ignition and dimming of the front panel lamps. Their number may vary from model to model. For convenience, we will use the most common number of indicators – five. The serial numbers of the lit LEDs will be located in brackets next to the alphanumeric code.

• E1 (1, 5) – excess liquid in the pan, activation of the Aquastop emergency system. Occurs when the sensor detects a leak at the pipe connection. This may also indicate a malfunction of the sensor itself. If water is actually in the sump, we can confidently talk about wear of gaskets, seals, and damage to pipes. Independent replacement is possible, but requires specialized tools in order to disassemble the PMM body.
• E2 (2, 5) – blocking of all device systems. There are problems with electrical wiring or other systems that may pose a possible hazard if you continue to use your Whirlpool dishwasher. For more detailed diagnostics, contact the service center.
• E3 (1, 2, 5) – error in the water heating system. Problems of this type include failure of the heating element (scale, wiring) and electronic temperature sensor. The faulty element must be replaced.
• E4 (3, 5) – temperature sensor failure. The most common reason is a voltage drop in the network. Such electronics are extremely sensitive to them. Replace the broken part with a new one.
• E5 (1, 3, 5) – excessively long collection of water into the working tank.The cause of this problem may be a closed water intake valve, a broken magnetic valve, the presence of foreign objects in the intake hose, or incorrect pressure sensor readings. First of all, check whether water is entering the system: open the valve and check the integrity and permeability of the hose through which water enters the machine. Clean the filter from dirt. Inspect the solenoid valve. Check the pressure switch pipe for blockages.
• E6 (2, 3, 5) – problems in the waste water drainage system. Occurs due to a blockage in the drain system (drain hose, filter), failure of the drain pump. Clean the hose, filter, and pump cavities. Check the pump's functionality. If a breakdown is detected, replace it.

"F" error codes

Error codes of this type will appear on the dishwasher display as F <alphabetic or numeric value>. After F there must be a character from the hexadecimal number system (0-9, A-E). Not all PMMs are equipped with a display. In such models, the value after F will be determined by the blinking of the START indicator. Their number will be indicated in brackets.

• F0 (10) – contamination sensor malfunction. An error can occur in cases where the sensor is heavily dirty, sends an incorrect signal to the control unit, the signal itself is completely absent, or there is a malfunction in the control unit. It is almost impossible to diagnose such electrical equipment at home; seek help from specialists. The faulty sensor or controller is replaced with a new one.
• F1 (1) – the temperature sensor returns an incorrect value to the central control unit. After inspection, it is replaced with a new one.
• F2 (2) – a water leak is detected, accumulating in the pan.The problem may be in the water supply or drainage system. Also check the integrity of the working tank itself. After detecting a leak, seal it, replace damaged gaskets and pipes.
• F3 (3) – error in the heating system. This code may be a consequence of failure of the heating element or temperature sensor (thermistor). The service center diagnoses all electrical components of this system. After this, the faulty elements are replaced.
• F4 (4) – water is not removed from the dishwasher after operation. A blockage in the drainage system, failure of the pump that is responsible for pumping out water, damage to the wiring. Clean the filter and hose, diagnose the pump systems. Replace faulty parts.
• F5 (5) – movement of the water sprayer is difficult or impossible. This occurs due to improper loading of dishes, exceeding the maximum permissible volume, or foreign objects getting into the sprinkler. Carefully inspect the part and the space around it. Remove all utensils if necessary. Do a test run. If this does not help, contact the Whirlpool service center.
• F6 (6) – malfunction of the water intake system. The inlet valve, valve, water flow sensor have failed, and a blockage has formed in the intake hose. Clean all elements of the system from debris and blockages. Replace the faulty sensor.
• F7 (7) – the flow sensor transmits incorrect data, the control unit does not respond to the request. Conduct diagnostics of the sensor itself, as well as adjacent wiring. Install a new sensor if necessary.
• F8 (8) – insufficient amount of liquid in the dishwasher tank.This code is displayed if too much foam has formed in the tank, the filter is clogged with food debris, and the sprinkler is not operating at full capacity. To resolve this problem, run a dry rinse and use less detergent.
• F9 (9) – water continues to flow into the working tank after the valve is closed. Malfunctions of this kind can be caused by a breakdown of the magnetic valve or control system. Replace faulty parts.
• F.A. (11) – malfunction of the OWI optical indicator. Occurs due to contamination of the lens and malfunction of the device itself. Try cleaning the lens yourself. If this does not help, contact a specialist.
• FB (12) – malfunction of the door (damper). This may be a consequence of a breakdown of the motor or closing system controller. It is better to carry out diagnostics and repairs at a service center.
• F.C. (13) – failure of the water hardness sensor. Inspect the sensor wiring. Replace non-functioning components.
• F.E. (15) – dishwasher software system error, failure of the built-in memory board. Replacing this component on your own is extremely difficult. Call Whirlpool specialists to your home.
