Dyson AM04 error code E4 any suggestions

E4 and E5 codes explained finally! E4 means motor is not spinning right, or reaching correct RPMs. E5 means heater in not working right. I will provide more detains next.
I had an AM05 which stopped working and it was showing E4 fault code and power light was blinking red. Occasionally as I turned it on motor would spin up for a second and then stop and fault code would display. Most of the time motor did not move. WARNING! I am an electrical engineer and have fixed countless things in my life, and I can say, taking this unit apart and putting it back together was very difficult. Do it at your own risk and of course, MAKE SURE POWER IS REMOVED WHEN WORKING ON IT.
First, remove the base ring and remove big screw in the middle. Next, disconnect the plastic white ring connected to the oscillating motor drive shaft. This requires removal of a C-Clip. (don't lose it, as it's likely to fly when being removed). Now pry apart the bottom section from the rest. Be careful as there are connecting wires all still there. Next, tilt the fan forward all the way and that will expose 4 screws in the rear, and when tilted the other was, two screws in the front. Remove them all. Now, disconnect connectors and start separating parts. Here are a couple of pictures I had taken.6da61f48-67d1-449b-a6d2-72e4af5aae9c.jpgdyson-am04-error-code-e4-any-suggestions-4e2m4lzwxx0at01yzka4mbe1-2-2.jpg
Of the two identical 6 or 7 pin connectors one has all red wires and the other is multicolor. When I disconnected the red one, the fault code went to E5. The red one goes to another board that has the heater circuit, so I deducted that E5 means either connections to the heater are bad, or heater is bad. I reconnected the red one and E4 came back. I disconnected the multicolor one and nothing happened, which told me the problem is there. I traced the wires and they were all going to the motor, which is further up the assembly. Getting to it was a real pain. To free the multicolor cable, you have to separate two rubber seals that allow the wires to move through an opening. If you can manage this, you can slowly get to the motor. When I turned the impeller I noticed that it was dragging, which explained the E4 code. When I turned it upside down motor spun freely and the fault code went away. So, I knew I had to fix the dragging problem, which was easy. Then putting it back together was a real pain. I recommend taking lots of pictures to remember what came from where. NOTE: There is thermal grease inter a metal heat sink. Make sure you don't wipe it off. It's essential, or heater semiconductors will overheat and fail. Also, MAKE SURE WIRES AT THE BOTTOM SECTION NEAR THE SWIVEL MECHANISM ARE DRESSED AS THEY WORE ORIGINALLY! Otherwise, they will rub and cam cause a fire. As you probably already know, there was a recall on these.
Anyway, hope this helps people. I have gotten so many great tips off the internet, I figured I had to contribute some as well.
God Bless.

E4 code on a bosch ghw 715 control unit

Before calling service technician, open following link for Bosch troubleshooting resources:

Error codes are starting point for troubleshooting, and solutions vary by model and unit.
E4 is Backflow temperature sensor over 309 degrees F. Appliance will close burner and lock.
Check combustion air and backflow vent piping for blockage.
Check if secondary fan connections are disconnected.
Check venting specifications are met. Long vent lengths, venting with more than three elbows, blocked vent or combination venting may cause this failure.
Check sensor resistance

Heayrt won't fire e4 can't hear fan runnung

I am not sure if you have gotten this issue corrected, or not, but the first thing I would try to do is to reset the heater computer system. This sometimes corrects and EO4 error code.

What you will do is open the right hand side door and find the POWER toggle switch, turn that off. Then find the CIRCUIT BREAKER for the heater and turn that off as well, then wait about 15 to 20 minutes. After waiting, you will turn the CIRCUIT BREAKER on first, then the heater. Try and start the heater up.

If the EO4 code comes back, there may be an issue with the heater. If the code does not come back and the heater starts, then the error code was what I call a "computer hic-cup".
