Sebo X4 2 red lights permanently ON
« on: June 12, 2022, 07:53:49 PM »
Any advice would be appreciated.....
Sebo X4 is maybe 10 years old.
My wife was using it and then it started making a weird noise and all 4 lights came on.
My wife tried it off and left it for me to get home.
I turned it on and it sounded OK but the two clog lights (bag and roller) are now on permanently.
Releasing the handle doesn't result in the automatic height adjustment that normally happens.

I removed the handle and removed the base top cover.
I found a screw rattling around inside.
It came from holding the height adjustment module.
I refitted it, refitted the base cover and ran the machine.
Sadly the two red lights are still coming on and no height adjustment.
Any ideas what might be wrong?

I think the control board is the old type with the potentiometer.
Regards
Adrian

Can you clarify where this screw came from please?

Hi, the loose screw was one of the two that hold down the height adjustment sensor mechanism, ie the large drum that is between the two drive belts and has the primary belt from the motor running round the outside of it.

It's most likely one of the PCBs at fault here, probably the top one.

It's hard to be completely sure without testing it in this case.
