FH error indicates that either you have no water coming into the washer, or very little water. Since you can see it filling, the error indicates low flow. A flow meter
in the unit detects if 10.5 gallons fills the tub within 8 minutes; yours must not be. This will turn off the inlet valves and the error code will be displayed. Check the following:

- Make sure you don't have a siphoning problem. This occurs when there is no air gap for the drain line at the standpipe. The standpipe is the drain pipe at the wall where the washer drain line is placed. With no air gap, a vacuum is created, and water will begin to drain from the wash tub prematurely. To prevent this from occurring, follow this advice:

•The standpipe should be 2 inches in diameter to allow a sufficient air gap between the top of the standpipe and the drain hose.
•The standpipe should be a minimum of 34" from the floor, and should not exceed 72 inches in height.
•DO NOT seal the top of the standpipe. Many consumers seal the standpipe in the belief that this will prevent overflows, or get rid of drain odors. This often creates more problems than solutions.
•DO NOT place the drain hose too far down into the pipe. Water stays in the drain trap area of the standpipe. If the end of the drain hose rests in this area, no air gap is created, and this can also cause siphoning. 4 to 6 inches is sufficient.
•The drain hose length must not exceed 10 feet in length. Excessive drain hose length can cause drain problems and back wash.
- Verify Drain Pump operation. Unplug the washer and take the lower panel under the door off by removing the three screws under the bottom edge. With the screws removed, the panel should drop down then come off. If it sticks, tap either side and it should come free. The pump is located directly under the wash tub in the front of the washer. Verify the electrical connections are good and that the pump is running. Open the pump access and remove, once you have all the water drained. Check the drain pump for foreign objects and debris. Check the pump impeller and make sure there's nothing caught in it. Items as small as toothpicks or cotton swabs have been known to stop this pump from working.


- Verify Flow meter operation and that the Pressure Switch hoses are intact and connected properly. Remove the three screws in the top panel along the back of the washer. With the screws removed, the panel should slide back, then, lift off. The flowmeter will be located on the left-hand side of the washer (facing from the front) between the inlet valve and dispenser. It's a small white plastic device with hoses attached. The pressure switch is located on the right-hand side of the washer in the rear. It is a round plastic device with electrical connections and a hose attached. There should be a tech sheet directly behind the panel or attached to one of the interior cabinet walls. Please refer to this sheet to learn how to perform diagnostics, how to locate the components mentioned, and the specific measurements required in determining if the components are good or bad.


"F/H" indicates that either you have no water coming into the washer, or very little water.

If you have NO water coming into the wash tub after 30 seconds the error code is displayed. Check the following:

- Inlet water valve may be clogged. Clean inlet screens if necessary.
- Make sure water taps are on.
- Check inlet hoses for kinks or clogs.

If you HAVE water filling the wash tub, and after 8 minutes, 10.5 gallons of water has been detected by the flowmeter, but there has not been a detected a Pressure Switch trip, the inlet valves are turned off and the error code is displayed. Check the following:

- Make sure you don't have a siphoning problem. Click the following link for instructions: http://www.fixya.com/support/r587481-prevent_washer_siphoning
- Verify Drain Pump operation.
- Verify Flowmeter operation.
- Verify the Pressure Switch hoses are intact and connected properly.

To access the Drain Pump - UNPLUG the washer and take the lower panel under the door off by removing the three screws under the bottom edge. HINT: Propping the front feet of the washer up can make access much easier. I use a couple small blocks of wood. With the screws removed, the panel should drop down then come off. If it sticks, tap either side and it should come free. The pump is located directly under the wash tub in the front of the washer. Verify the electrical connections are good and that the pump is running. If not, click on the following link to check the pump for obstructions:

"F11" is a Serial Communications error between the Central Control Unit (CCU) and Motor Control Unit (MCU). The CCU is the main computer for the washer and is located directly behind the wash tub. The MCU is the Drive Motor Control board and is located in the rear of the washer adjacent to the Drive Motor on the left-hand side (facing from the rear with the back panel removed). The wiring harness can also cause the error, but it is not as common a problem.

Whirlpool is the manufacturer of both model washers and recommends the following troubleshooting advice. Remove the top panel of the washer by removing the three screws holding it in place in the rear. Once the screws are removed, the panel slides back, then off. Remove the rear panel of the washer for access to the drive motor and MCU. Now check the following:

- Check the wire harness connections between the CCU, the MCU and Drive Motor. Make sure all connections are attached and making good contact. Check for any broken wires or connector pins.
- Check the Drive Motor to see if it free spins and that the belt is still attached and not slipping. If the motor is seized, replace it. If the belt is broken or worn, replace it as well.
- Check the MCU. Connector 1 is the Serial Communications Link between the MCU and CCU. Connector 2 is the connector to the drive motor. Resistance checks across pins 1, 2, & 3 are the motor windings. Connector 3 is the power supply - 120VAC should be read across pins 1 and 2 with the door in the locked position. NOTE: The connectors are read 1, 2, and 3 from the bottom to the top with the MCU installed.
- Check the CCU. Verify connectors 7 and 11 are properly installed. Facing from the front of the washer, connector 7 is the 4th connector from the RIGHT along the front. This is MCU Power. Connector 11 is the Serial Communications link from the CCU to the MCU and is located along the left hand side of the CCU (the connectors are numbered 11 through 14 back to front).
- Check the Drive Motor. Remove the connector and perform resistance checks on the motor connector pins. Readings across pins 1 to 2, 2 to 3 and 1 to 3 should read 6 ohms.

In most cases this is an indication of a failed CCU. This is an easy repair that the average do-it-yourselfer can accomplish on their own. If the washer is still under a warranty, parts and labor would be covered. With no warranty, a replacement parts will vary in price depending on where you get them. There are several good websites available that you can order parts on line and have shipped directly to you.


NOTE: Remove all the connectors from the CCU ONE AT A TIME and reconnect to see if the error code goes away BEFORE you decide to purchase a new one. It is not common, but sometimes a flaky connection can generate error codes.

What does the F11 error code on my Kenmore Elite He 3t mean?


"F11" is a serial communications error. The following link explains the possible causes and how to troubleshoot:

http://www.fixya.com/support/r666194-f11_error_whirpool_duet_kenmore_elite

First, attempt to unplug the washer for AT LEAST 30 minutes in an attempt to reset the Central Control Unit (CCU). In many cases, this is all that is required in order to correct momentary glitches with the unit. If the error code reappears, follow the advice provided in the link. In the majority of the cases, I've experienced, it was the CCU that caused the problem.

If you have questions, or require additional assistance, please let me know. I hope this helps you.

F11 flashing kenmore he washer


The F11 error code indicates a serial communication failure. This happens when the 2 main control boards are unable to communicate with each other. This is either caused by a loose wiring harness connection or one of the control boards is defective. Good luck and please rate FixYa!

Kenmore Elite H3 error code F11


F11 is a serial communication error. It is recomended to check connections from the motor control unit to the ccu. We are looking for the blue wires that carry info from component to component. The ccu is on top under the cover positioned in back for older machines and front right for new machines. The mcu, motor control unit is behind the kick panel below the door and is front left usually.Again we want to unplug check for dark or crusty connections if not to carefully reseat the connection and not only the blue serial wires but power as well. Remember to first unplug the machine and while you work the machine can reset, 30 minutes is typical.

Error F11


Plug off the wall. Shaking & vibration of your washer causes circuit board connections to become loose; due to faulty manufacture. Remove the 3 or 4 screws from the back & take off the top cover to secure the connections, make sure they are tight. This applies for the F11 & F dl codes. Works for certain machines, dont see why it wont for yours.

Error code F11 and orthers


gailo, F11 is a serial communication error. Communication between the central control unit and the motor control unit cannot be sent correctly. Possible solutions: Check the harness between the two boards for loose connection. Driver motor, main board or motor control board may be bad. I have come across a number of these with loose connections and bad main boards. Put it into a test by pressing drain/spin on the left side. Then press the spin speed button on the right until no spin is lit. Then press the pre-wash button on the right 4 times until 00 comes up in the display. You are now in the automatic test mode. Let it do it's thing about 15 minutes and see if the error comes again. Catriver...post back.
