WF37 lack of water
or EL1 or EG1/EG2
Measure the
pressure
downstream the
pressure reducer
when the oven is
cleaning
YES
NO
Measure the
pressure upstream
the pressure
reducer
NO
The pressure doesn’t match
the UNOX technical
specificaons
NO
Replace the power
board
Is the tap water
open?
NO
Open the tap water
YES
Replace the
pressure reducer
Replace the EL1
valve
Test 3
The oven checks if
there is water, if EL1
does not open or if
EG1/EG2 do not close
YES
YES
Replace the power
board
NO
YES
Replace the EG1/
EG2 valve
NO
NO
Does the alarm
disapear?
YES
End
NO
Replace the pressure
switch
EL1 is the most probable
cause of this alarm
YES
Replace the power
board
Maybe chemical is in
the cooking chamber
Do you have
a
value of pressure in the
range 1,5 - 2 bar
(21.8 – 29 psi)?
Test if the
pressure switch closes the
circuit with the mulmeter
set to ohm. Does it close
the circuit?
Take out the
EG1/EG2 valve and check
if it is blocked open by blowing
through it. Is the
valve open?
Measure with
themulmeter set to V AC
if the power board supplies 230 V AC
to the connector of the water
solenoid. Is the EG1/EG2
supplied?
Measure with the
mulmeter set to V AC if
the power board supplies
230 V AC to the connector
of the water solenoid.
Is the EL1
supplied?
