E4
Remedy
 The error E4 can have
different causes:
1. The voltage is too high for a
short time, 28 ... 30V, causing
the motor to run too short.
2. The connected supply
voltage was too low, then the
motor will run too long.
In these cases the error is
eliminated by switching the
FlexxPump off and on.
Important! At least 60 seconds
must pass between switching
off and on!
If this does not correct the E4
error, dismantle the FlexxPump
125 and send it back to the
manufacturer together with
the lubricant cartridge and a
description of the error.
The address of the
manufacturer can be found in
chapter I.II.
