Error message E27 appears and washer won't operate.

In the instructions for different models of Bosch dishwashers, the e27 error is described as insufficient voltage in the electrical network. This means that if the mains voltage drops below 220V (or 110V in some countries), the dishwasher stops working, and the E27 error code appears.

1. Set the knob to off.
2. Hold down both the Spin Selector button and the Allergy Rinse button simultaneously.
3. While holding these two buttons down, rotate the knob one click to the left, to the "cold" position.
4. At that point, the display will show a diagnostic code and the unit will enter a self-test mode. In my case, the solenoid latch started clicking repeatedly. I pressed the Spin Selector button once or twice, which resulted in the display of new codes and then the release of the latch.
5. I set the knob back to off, and the washer now appears to be operating.
6. You're done.

Here is what worked...

the two possibles are faulty door lock or water still in the machine. the error code should tell you which. go to AEG and their troubleshooting page will give you the codes.

Each cartridge having printing life, as long as cartridge health condition is good it won't gives any trouble. Subjected series printer having mono & colour cartridges,1. Remove both cartridge from the printer 2. Switch on & wait till message appears for insert the cartridges..3. Insert mono(Black) cartridge, close the door & wait till message appears on screen. If message appears same as cartridge error mean that mono cartridge is faulty replace it, if message appears like insert another cartridge, it's confirmed that colour cartridge faulty.. Replace it..

If it copies ok, then the issue is either the way it is cabled to computer or the print driver software settings on pc.... How is it connected via USB? Check port and correct driver is in windows/control panel/printers. Reinstall.

HP B8550 has no numeric keyboard, so those solutions won't help.

E27 means you have a problem with the door lock . It could be the door is not shut all the way or the lock assembly is just bad and needs to be replaced. If you have turned the unit off and back on from the power supply I would say you probably need to replace the door lock.

It is recommended that remove power from the appliance (unplug it) for 30 minutes and try again. If this doesn't remedy the error code, you'll need to schedule a service call.

Hope helps.

Hi

An "F-11" error code on a Whirlpool Duet could cause your washer to become inoperable and stop in the middle of a load. The cause of the problem could be a number of things and may require new parts.
F11 can mean anything from motor to motor control board to ccu board to wiring harness connecting ccu to mcu to motor.

Identification

The "F-11" code could appear with the dash or without the dash on the LCD screen. Be aware that there is also an "F-H" code that could look similar to the "F-11" code. Listen for 11 beeps to go along with the error code's first appearance.

Effects

The error means that there is no communication between the "Motor Control Unit" and the "Central Control Unit." This means that any operation selected like "Pre-wash" or "Large Load" cannot be sent to the motor for the washer to operate.

Prevention/Solution

Open up the washer panel to check the wire connections between the two units. If any plugs are loose or unplugged, reconnect them. Check to make sure none of the wires are stripped, rusty or broken off. After you reconnect the wires, rerun the washer to see if the error appears again.

Warning

If you do not know or understand the inside components of your Whirlpool washer, leave the job to a professional. Contact the store where you purchased the washer or Whirlpool customer service directly.

Please get back to us if you have further query else please accept the suggestion.

The E27 code isn't often listed in Bosch manuals but relates to the washer door lock.

The E27 error flashes on the washer LCD screen and stops the current load. Unplug your washer for 30 minutes and then plug it back in to reset the code.

Open and close the door two or three times to reset the sensor. Sometimes the door has been closed too hard and the sensor reading fails.

You may need to replace the door lock assembly on the washer.
