wF16 - laCK oF water or el1
WF16 lack of water
or EL1
Measure the pressure
downstream the
pressure reducer
when the oven is
cleaning
NO
Do you have a value
of pressure in the range 1,5
- 2 bar (21.8 – 29 psi)?
Measure the pressure
upstream the
pressure reducer
Do you havea
value over 1,5 bar
(21.8 psi)?
The pressure doesn’t match the
UNOX technical specifications
Replace the power
board
NO
Replace the EL1
NO
Measure with the
multimeter˘set to V AC
if the
power board provides
230 V AC to the connector
of the water solenoid.
Is the EL1 power on?
YES
Does the EL1 open the
flux of water (remove the
pressure switch and place
a manometer to measure
a pressure increase)?
YES
Does the EL2
close perfectly? Verify if you
have any leakage
of water
Is the tap water
open?
Open the tap water
Replace the pressure
reducer
Replace the EL2
NO
YES
Test if the pressure
switch close the circuit with
the multimeter set to ohm.
Does it close
the circuit?
Replace the power
board
Replace the pressure
switch
Test 1
Test 2
Test 3
Update the firmware to the latest.
Load model parameter. Check the
correct type of solenoid valve set on
service menu, oven setup, washing.
