It turned out that there is a breakdown on the winding of the hydraulic motor.

first make sure that your brake pressure is good check the two lower solenoid valves in the valve block whether there is any dirt between themAt the

moment of driving or stopping, your brake is operated if your pressure is not right you get an alarm

225 Pump motor does not run up to speed although a control signal is present
347 Pressure in brake pressure accumulator <25 bar
800-863 Fault in the Lifting power unit

I have exactly the same problem. LINDE E16 - 386-01.
Such errors pop up on the display. First L810, then L225 and L347. Replacing the pump motor rotation sensor did not help. There are moments when the trolley works without any problems, and the longer I use the trolley, the more often errors appear.

Do you have a solution to this problem?

hi Rodrigo
ur email then i can send you something

Hello gc_d!

Thanks a lot for your help.
I have checked the sensor and I didn't find any problems.
The fault is intermittently and just happen when I put the joystick on "zero" position. I suppose the pump it's not keeping the right pressure on the system. Some times happen when I use the traction also. Is the letter L in the begin of the code a Lift fault? If yes why is happen when I'm traveling?
I apriciate if you can help me!

Best Regards,
Rodrigo.

L810 is speed sensor error pump , check pump and sensors or replace sensor
