Symptom Problem Solution
The electrical
oven does not
heat
A phase is missing
Try to plug the oven to another socket and run the oven. If the oven
works properly call an electrician, otherwise follow the next steps
Either the heating
elements or the
contactors are
damaged
Measure the amp consumption of the oven with the clamp meter
directly on the terminal block.
■ If the phase consumption does not match the technical data available
on Infonet, check if the contactors close the circuit.if they do not close
the circuit, check between A1 and A2 PIN with the multimeter set to V
AC
■ if the power board supplies 230 V AC to the contactor turn.
■ If the power board does not feed the contactors replace it, otherwise
replace the contactors;
Measure the amp consumption of each heating element turns.
■ If you find 0 A in at least one turn replace the element
The cleaning
cycle is not
effective
The inlet water
pressure is not
enough
Measure the inlet water pressure with a pressure gauge. Do you have a
value within the range 1.5 < p < 6 bar?
■ If not, the water pressure is not in compliance with the UNOX specifica-
tion
■ If yes, measure the pressure downstream the pressure reducer with a
pressure gauge. Do you have a pressure equal to 2 bar?
■ If not, replace the pressure reducer
■ If yes, go on with the troubleshooting
The power supply
to the chemical
pump is not
enough
Measure the power supply applied to the pump with a multimeter set
to V AC. Do you have a power supply of 120 – 140 V AC?
■ If not, replace the power board
■ If yes, go on with the troubleshooting
The oven does
not pump in the
chemical
Is the chemic󵄍󱀇󵤍er free of residuals?
■ If not, replace the filter
■ If yes, is the pipe downstream the pump free of residuals?
■ If not, replace the pipe
■ If yes, replace the pum
The oven does not
pump in water
Is the tap water open?
■ If not, open the tap
■ If yes, do you have power supply to the water solenoid measuring with
the multimeter set to V AC?
■ If not, replace the power board
■ If yes, is the water pipe clogged?
■ If yes, clean the pipe and check the water quality according to
UNOX specifications in terms of water chemical composition
■ If not, replace the water solenoid
The end user runs
the cleaning cycle
with the trays
inside the cooking
chamber
Remove the trays from the cooking chamber before running a cleaning
cycle
The end user does
not use the UNOX
Det&Rinse chemical
The frequency of
the cleaning cycle
is not enough
compared with
what they cook
and the cooking
program frequency
Train the end user about the importance to clean the oven with the
proper frequency
211
The installation is not in compliance with the UNOX specification.
