Heater Level Switch (Heater Pressure Switch); Table 4-9: Circulation And Drain Pump Data - Miele G 600 Series Technical Information

G 600/G 800
During dishwashing, the circulation pump (M6) takes in the wash water from the side
of the sump through the microfine filter and the large surface area filter and pumps it
to the spray arms. During drainage, the drain pump removes water out from below
the microfine filter. This change of direction in the water flow assists in flushing out
any residues that may have been retained within the filter. Water passes through the
non-return valve and then to the on-site drain.
A bimetallic switch is integrated into the circulation pump motor windings and serves
as a safety cutoff should the temperature exceed 150°C (302°F). After a cooling-
down phase, which can be anywhere from 10 minutes to 1 hour, the switch resets
automatically. If the switch is faulty, the circulation pump motor assembly must be
replaced.

Heater Level Switch (Heater Pressure Switch)

Heater pressure switch B1/10 is located directly on the circulation pump and
actuates when water is present and circulating (producing pressure). The switch is
monitored by the electronic and is electrically in series with the heater relay.
If sufficient water and circulation is not present the switch is not actuated; this keeps
the heater relay circuit interrupted, which causes the appliance to malfunction and a
fault to be stored in the electronic.
Should the switch be faulty and remain constantly actuated, the appliance will
malfunction and a fault will be stored in the electronic.
