eppendorf 5810R board diagnostics
- convertor is overloaded; allow unit to cool and retry after 5 minutes
- the brake is defective; no remedy given in the manual for this!
- the voltage supply is too low; check voltage supply to unit
- the rotor has come loose; retighten rotor
If the unit has just been moved, first thing I'd try is removing then refitting the rotor. If this doesn't work I'd check the voltage. If its been left switched on for a long time it might not have appreciated being switched off while it was being moved, so it might have blown something on the voltage regulator (where the power cord goes into the back of the unit).
I hope you manage to sort it out - my 9 year old 5810R died last month due to the rotor sensor failing. Eppendorf claimed they only keep spare parts on equipment for 7 years and since mine was 9 years old, no spare parts were available. Unfortunately, I had to scrap the centrifuge. Hope you have more luck with yours!
All the best
Were you able to fix the error 6 on your machine? Please let me know. Also, do you have the service manual?
Hallo, I have the same problem - error 6. Does anybody have service manual to send me? Thanks!! Reno , My adress E-mail: firstname.lastname@example.org
LabWrench has a partial User Manual for the Eppendorf 5804 / 5804R / 5810 / 5810R Centrifuges posted on the DOCUMENTS tab of the product page.
Below is a direct link to the User Manual.
The error codes are noted on page 41.
Please feel free to contact me if you have any questions.
thank you very much for User manual!
Do you have service manuel too?
Thanks and regards
No we do not have the Service Manual here. There are many publications on the Eppendorf Website:
Click on the following links
1. Support and ep Services
2. Literature Library
There you will find a list of products to choose from.
Sorry for my english .
Usualy the problem ( in the case of error 6 - over load ) it's in a IGBT conected betwen the bridge rectifier and the brake resistor located in the inverter module.
This module it's the module conected to the motor.
sorry my english but today i've repaired another centrifuge with the same problem.
Please don,t hesitate to contact me.
All the best
I replaced two biggest electrolytic capacitor on frequency convertor board - it solved problem. (there was error 6)
regards Reno Zagreb
I have a fault with this centrifuge with lid lock issue. When trying to close the top lid, the motor tries to latch the lid but stops half way. after few tries it does close, but fails to open the lid when button is pressed. I have replaced the lid lock motor and the lid microswitches but fault remains. I have monitored the motor voltage. there motor works without load, but voltage cuts off as soon as load is applied to it.
any suggessions on what might be causing the motor voltage to cut off??
also link to service manual would be helpfull.
Here are links to the service manual. Sorry I had to break it into 3 parts, due to email server limitations.

Do you have a diagram to illustrate how to make this repair. I have a 5810R that is throw me an error 6. The centrifuge continue to cool down and everthing else appears normal unitl i start a run and it indicates an error 6??? could you help me out?

You are awesome. Was looking for the service manual everywhere for my centrifgue 5804.
Does anyone know where I can get a schematic of the Control card for the 5810R?
Did you ever manage to get a service manual for the 5810R?. and if you did would you be able to send it to me?
Check the link above, there is a service manual available in 3 parts.
There are two different versions of the 5810, an older one and a newer one. The manuals from the link given above are for the newer model. I have the older machine and someone sent me the older manual. All of these manuals are scanned copies so the schematic pages are almost impossible to read. Eppendorf sent me the original PDFs for some of these schematics. I forwarded them to the Admin here but I haven't seen them post a link for them yet.
My machine gives an error 6. I was able to find that a trace on the main board had burned open. This trace supplies power to the frequency convertor card. Examination of that card shows a very slight deforming of the two large capacitors on it. I can't readily see how to seperate this card from the metal base it is attached to. Reno in a post above says he replaced two capacitors to fix his machine.
Hey RENO! If you're listening can you tell me how you did that?
Just to give you a trick, i had to replace a part and the metal base was driving me nuts. I drilled two holes right behind the connectors and resoldered the part. Worked fine and i dont think there is any other way.
jjj, would you mind posting the service manual for the older 5810R? We are currently servicing a unit showing Error 6, and would find the manual very helpful!
jjjj, can please post the service manual for the older version? It would also be helpful to me.
Thsanks in advance
I sent the manual to Admin. If you post an email I will try to send it to you directly.
Hey jjj, you can send it to

My centrifuge 5804 R showing error 2. The only way to run the centrifuge is to run instantly after closing the lid. otherwise, after 2-3 seconds of closing the door the error 2 comes and not allow to start centriguge.
Is there a way to reset error 2?
Dear Alexan. Your error is related to imbalance sensor. Check the brown-yellow-green-white ribbon cable connections at the board. You can take it out and in, clean the pins. If not solved do the following: with the centrifuge lid open push both arrow keys, display will change. press up until you see as first digit "6:". You should have a value of 670 +/- 100 there. If you move the rotor axis this value should change. If the value displayed is out of range, the imbalance sensor should be readjusted.
please check this and post your results in order to help you further.
Could you send me a link to the old service manual too?

Awesome! Thanks a lot for that Service Manual. It just helped us to get a centrifuge running again after an "Error 2" after we had to remove a lot of rust and dirt out of an old centrifuge!
Adjusting the imbalance-sensor still is a huge pain! :)
I have an old 5810R. When power it on, it always ask me to press open lid. Once I open and close the lid, it gives error 2 immediately. I've adjust the imbalance sensor to 667 followed by the service manual, the problem still exist, re-check the balance sensor, still with in the spec 670+/-30.
