5.13 Fault List
Following is list of fault conditions and most possible causes.
Door Open Fault – Not confirmed door closed
(i.e. door switch still indicates open)
• Door limit switch stuck out / broken
Wash / Disinfection Cycle Time Out
(taking too long to complete cycle)
• Steam leak
• Final rinse solenoid stuck open
• Faulty temperature sensor - hot water tank
• Blown element leg
• Steam condensate leaking cold water into chamber
• Faulty temperature sensor - chamber
Faulty Hot Water Probes
(high indicates water, but low does not indicate water)
• Faulty water level probe
Door motor activation time out
(taking too long to close or open door)
• Faulty door actuator
• Door axle bar sticking
Hot water tank fill time exceeded
(high level not reached during pre-fill, resulting in time out)
• Faulty fill solenoid
• Faulty water level probe
• Cold water tank empty or not filling quick enough
• Low water pressure
Hot water tank low water level sensed during cycle
• Faulty water level probe
• Cold water tank empty or not filling quick enough
• Leaking tank or hose
• Element stuck on
• Condensing coil blocked
Door closure fault – not confirmed door open
(door switch still indicates closed)
• Door limit switch stuck on
Failed to reach disinfection start temperature, resulting in time out
• Steam leak
• Final rinse solenoid stuck open
• Faulty temperature sensor hot water tank
• Blown element leg
• Steam condensate leaking cold water into chamber
• Faulty temperature sensor chamber
• Door not reaching interlocking micro switch
• Door not fully closed
• Over temperature board (power to element open circuit)
• Element over temp protection manual reset thermal cut-out
switch open circuit
