6.1 – FAULT FINDING
Alarm light and LED
Faults are reported by the flashing alarm light on the wall mounted panel and this is
replicated in the cooler by the LED
When the cooler enters an alarm condition the LED on the wall controller flashes to give
an indication of the problem. There are 6 different alarms which are identified in this way.
1 flash – Slow fill Auto reset
If the high level probe is not covered within 20 minutes this means there is a water supply
problem.
Possible causes:
• Water supply not turned on – turn water on
• Filter on inlet to solenoid blocked– clean filter
• Drain valve held partially open by debris – clear/clean drain
• Solenoid valves failed
Diagnostic :
• Use test sequence to check
• 12VAC should be present between contacts V1 and V2 on control board. If
voltage is present and valves not operating replace valves
• Check 12VAC output from transformer – repair/replace as necessary
• If OK then main board failure
2 flashes – Overflow Manual reset
This is activated when the HH Level probe is covered.
Possible causes
• Water inlet valve solenoid failure
• H probe failure
