level during heating, then

the heater is switched off for 2 minutes. It will only be switched on again
when the pressure increase drops to 0.6” wc above wash level; no fault
message for target temperature not reached is issued,

if foam sensing occurs three times, the fault message Check dosage is
issued at program end,

if foam sensing occurs three times, the fault message F 16 Oversudsing
is saved in the fault memory; refer to Section 070-3.17.
2.1.2 Foam at Rinse Cycle Water Intake (in the Drum Vent or Siphon)
If foam is generated during rinsing, the pressure in the suds container
rises more quickly than it would based on the water intake.
If the imbalance sensor registers a pressure increase of more than 1.6”
wc within 4 seconds during water intake, then

the water intake is interrupted for at least 15 seconds,

the water intake will only continue when the pressure increase drops to
0.6” wc,

the fault message Check dosage is issued at program end,

the fault message F 16 Oversudsing is saved in the fault memory; refer
to Section 070-3.17.
2.1.3 Foam during Spin Cycle (Water Sheet)
The spin cycle generates foam, and a water sheet is formed. The pressure
increases, and the water sheet acts as a brake on the drum.
If the pressure sensor registers a higher pressure than is expected for a spin
speed during a spin cycle, or if the target/actual speed difference is higher
than expected, then

the rpm is reduced, or the spin cycle is stopped,

an additional rinse cycle is carried out if the spin cycle did not go for at
least 60 seconds at 700 rpm.

the fault message Check dosage is issued at program end,

the fault message F 16 Oversudsing is saved in the fault memory; refer
to Section 070-3.17.
2.2 Light in the Door Concertina Seal
LED light in door seal.
2.3 Heater
Thermal cutout:
To protect the appliance from overheating in the case of a technical
malfunction, e.g., if a heater relay is “stuck”, the heater element is equipped
with an integrated thermal cutout.
If the thermal cutout trips, the heater element is destroyed.
