Subject	Water Leakage at the Rear Window of CWS machines
Model	Undercounter LS6EA / WT38 and Hood Type LS14EA / WT65E with
	Continuous Water Softener built-in.
Problem	Water leakage from the rear open window (air break).
Reason	Tank filling not properly set or boiler/tank filling not working properly.
Action in	Since serial number 61700001 we have introduced the firmware release
Factory	4.0260004 in main boards 0L0731 (not lead-free) and 0L1238 (lead-free) with
	following new features:
	• Disabled tank filling by boiler overflow whether SEr = 9 even if btF = 0.
	Therefore Undercounter/Hood Type with Continuous Water Softener built-
	in are always filled by short rinse cycles (btF = 75 as standard).
	• Disabled tank filling by boiler overflow if the water level decreases
	because of:
	1.	level switch malfunctioning
	2.	over-flow pipe not fitted properly
	3.	drain cycle / self-cleaning cycle stop manually before the end
	4.	opening door during drain cycle / self-cleaning cycle
	5.	drain hose connected as for gravity drainage instead of having outlet
		between 750 mm and 1000 mm from the floor (see handbook).

Therefore Undercounter/Hood Type with Continuous Water Softener builtin are always filled by short rinse cycles.

• Decreased inlet valve delay from 3 seconds to 2 seconds since reed sensor at the rear has open circuit (float level switch is in upper position).

This parameter cannot be changed by the user interface.
