7.0 SERVICE (Continued)
WATER OVERFLOWS INTO COOKING COMPARTMENT
When steamer is first turned on for the day, and the following conditions occur:
- READY light does not come on after about 15 minutes,
- Water begins to overflow into cooking compartment,
- Water fill solenoid valve is open,
then any or all of these symptoms may indicate a problem with the operating probe due to
either:
1. A short between the operating probe terminal and body of the steamer. Call your authorized
service agent.
2. Excessive scale build-up on the operating probe. This acts as an "insulation" and prevents
the probe from sensing the water level. It is therefore unable to close the water fill
(solenoid) valve to shut off the water.
As a temporary solution, with power OFF, unscrew probes, check visually, and clean or chip
off scalant. Replace probe.
This problem is an indication of severe harmful water conditions which should be corrected
immediately to avoid damage to the components and ultimate malfunction of the steamer.
(See WATER CONDITIONING in this manual).
HEATER ELEMENTS DO NOT COME ON
When the steamer is turned ON and heater elements do not activate, and therefore, the READY
light does not come on, then the contactors may be burned out. If a considerable amount of
"chattering" of contactors has been previously experienced, then the thermostat bulb may be
coated with scalant and unable to sense water temperature in the boiler accurately, and
therefore unable to control the contactors.
1. Replace contactors.
2. Unscrew operating thermostat bulb, clean off scalants and screw thermostat bulb back in.
This problem is an indication of inadequate water quality and is not covered under warranty.
Have water quality analysed and corrected immediately to avoid complete malfunction of the
steamer.
