Steam down time
Heater element (s) is/are
driven but water level
remains constant
•
Heater element is
defective
•
Measure heater ele-
ment resistance,
replace heater ele-
ment, if rquired.
Typical resistance va-
lues are:
SLH03
- 2.25kW/230V
- 21.3...26.1Ω
SLH06
– 4.5kW/400V
– 32.3...39.5Ω
SLH09
– 6,75kW/
400V - 21.5...26.3Ω
SLH15
– 3.8kW/400V
– 38.2...46.8Ω (3x)
SLH25
– 6.3kW/400V
– 23.1...28.2Ω (3x)
SLH40
– 6.3kW/400V
– 23.1...28.2Ω (3x) +
3.8kW/400V –
38.2...46.8Ω (3x)
SLH50
– 6.3kW/400V
– 23.1...28.2Ω (6x)
•
Phase loss (external
circuit breaker has
tripped or is defective)
•
Check circuit
breaker, find reason
for tripping
•
No voltage supplied
to heater element(s)
•
Check wiring, mea-
sure voltage
•
No proper main con-
tactor switching action
•
Check and replace
main contactor, if
required
•
Main contactor is not
energised by PCB
•
Verify voltage across
PCB terminal 9 and N
124
Main contactor coil
Voltage detected across coil
thoug main contactor is not
driven by control logic
•
Relay K4 on main
PCB is stuck
•
Replace relay

tive
•
Check sensor cable
•
Sensor defective
•
Replace sensor
