HELP CODE H51 : OVERFLOW FAILURE
When the water level is raising above the hole of the overflow tube: Help Code H51 will be displayed.
DIAGNOSE(ERR21):
1. Check if the overflow hole and tube isn't
blocked
2. Check if the drain tube isn't blocked
3. Check the water inlet valves
4. Check the output relay that powers the inlet
valve
HELP CODE H52 : WRONG INPUT (UNBALANCE)
Help Code H52 occurs when the input for tilt switch F- machines has been wired.
For safety reasons this input must stay low on MFR machines.
DIAGNOSE(ERR68):
1. Input (FS tilt) must not be wired and must have
low voltage.
HELP CODE H53 : RS7 Select
Wrong machine type has been selected. MFR18 has been selected in stead of MFR25.
Select the right machine type. (See machine type plate at the rear side of the washing machine)
HELP CODE H54 : RS10 Select
Wrong machine type has been selected. MFR25 has been selected in stead of MFR18.
Select the right machine type. (See machine type plate at the rear side of the washing machine)

HELP CODE H55 : Slow Refill
After the fill sequence (machine has already taken the right amount of water to wash), the machine fails to
refill in case there is a leak.
Diagnostic evaluation see D7 : Slow Fill.
Help Code H55 is for informative purposes only and doesn't result in an Error handling procedure.
HELP CODE H56 : No Internal Clock
Help Code H56 occurs when the Internal Clock of the wash computer is not functional anymore.
As a consequence the wash computer Day and Time calculation will be stopped and the function for automatic
switching between Normal & Special Pricing will be disturbed.
This will probably be a hardware failure of the wash computer.
HELP CODE H57 : NO SIGN SPIN
MFR18 - MFR25 only. Help Code H57 occurs when there is no feedback speed signal from the Motor Drive
at the spin sequence. Probably this also means that the drum is not turning.
DIAGNOSE(ERR68):
1. Check the communication cable.
2. Check the motor drive.
3. Check the motor.
4. Check the power cable to the motor drive
and also to the motor.
5. Check the output relay that powers the
