The heaters are supplied
with current, but water level
doesnot change.
•
Heater element is de-
fective.
•
Measure heater ele-
ment resistance; re-
place heater element,
if required. Nominal re-
sistance values are:
FLH03
- 2.25 kW / 230
V - 21.3 - 26.1
Ω
FLH06
– 4.5 kW / 400
V – 32.3 - 39.5
Ω
FLH09
– 6.75 kW /
400 V - 21.5 - 26.3
Ω
FLH15
– 3.8 kW / 400
V – 38.2 - 46.8
Ω
(3x)
FLH25
– 6.3 kW / 400
V – 23.1 - 28.2
Ω
(3x)
FLH30 –
3.8k W / 400
V
- 38.2-46.8
Ω
(6x)
FLH40
– 6.3 kW / 400
V – 23.1 - 28.2
Ω
(3x)
+ 3.8 kW / 400 V –
38.2 - 46.8

•
Phase failure (exter-
nal circuit breaker has
tripped or is defective)
•
Replace external cir-
cuit breaker, eliminate
cause for tripping
•
Heater elements not
supplied with voltage
•
Check wiring and
voltage supply
•
Main contactor
swiching not o.k.
•
Check main contac-
tor, replace if required.
•
Main contactor not
driven by mainboard
relay
•
Measure voltage on
mainboard terminal 9
against N; replace
mainboard, if required
