VERSION: 2.0
TITLE: Over foaming when washing with liquid detergent.
SUBJECT: There are some cases in the field of over foaming and detergent coming out of soap dispenser area during
filling phase. This can occur when there is liquid detergent used.
CAUSE
When the water inlet has got a high pressure and splashes to the liquid detergent in the dispenser box, this creates much
more foam than the inlet system and especially the separator is designed for.
REMEDIAL ACTION
In case of over foaming at the customer:
The correct assembly of inlet hose between detergent box and tub has to be checked.
If it's correct, the separator needs to be replaced by a modified one, that has got a wider slot (expanded from I=1mm to I=
2.5mm) in the middle in order to increase the flow rate and avoid over foaming.
New part SC: 4812 418 89066 (same code like old one. Stock has been exchanged).
From week 27/2008 onwards in production the modified separator is included.
REMEDIAL ACTION
If after exchanging the separator still over foaming occurs, it's possible to order a flow rate limiter set 4801 310 00098
containing of a flow rate limiter and a sieve.
