Safety devices
• An automatic reset thermoamperometric protective
device incorporated in the windings of the electric
pump cuts off the electricity supply in the case of
malfunctioning.
• In the event of water mains failure, a device pre-
vents water in the boiler from returning into the
mains.
• An overflow pipe, connected to the drainage outlet,
maintains the water in the tank at a constant level.
• On models with a drain pump, a supplementary
level control device activates if the main level con-
trol device is faulty.
Failure to comply with safety rules and regulations
relieves the manufacturer of all liability.
B3 WARNING MESSAGES DISPLAYED ON THE
CONTROL PANEL
NO WATER
- Check that the cock is open.
- Check that the water inlet filter is clean.
- Check the minimum mains pressure.
- Check that the overflow pipe is inserted (for appli-
ances without drain pump only).
INEFFICIENT DRAINAGE
- Check if the overflow has been removed.
- Check for obstruction on the waste outlet pipe and
the overflow aperture.
TANK WATER LEVEL TOO HIGH
- Check for obstruction on the waste outlet pipe and
the overflow aperture.

CAUTION
A normally open (n.o.) contact of the con-
troller must be connected across termi-
nals 11 and 12. When this contact closes
the boiler heating elements are discon-
nected. Using the dishwasher in these
conditions may increase the cycle time.
