Oven behaviour
Solution
W1
Power board heat sink temperature too high.
The heat sink is a special aluminium block, fitted onto the power board to dissipate
the heat this generates.
If these warnings are displayed, the oven continues to work but shows some anomalies connected
with the excessive temperature that must be solved.
Check:
•
the oven is positioned correctly (e.g. the temperature of the room the oven is installed in)
•
the recommended distances from walls and appliances that generate heat (e.g. fryers)
•
if the cooling fans are working (looking through the vents without removing the side)
Once these checks have been made, if the problem remains, contact Technical Service.
W2
Cold junction temperature too high.
The cold junction is a sensor built into the display board that detects the tempera-
ture of the latter and the surrounding atmosphere.
W3
The oven is fitted with a meter counting the working hours: after 250 hours, a pop-up
warns the user that cleaning under the refractory surface is required.
If you touch the pop-up, it disappears but remains as a warning in the taskbar. We recommend
cleaning under the refractory surface is carried out as soon as possible.
