Technical Information
G1000 / G2000 Dishwashers
a. If pluses are present, the electronic board needs to be replaced.
b. If pluses are not present, first check wire connections for an open or short
circuit. Replace the slide shutter drive if necessary.
3. If the slide shutter gearing or the drive (synchronous motor) is defective. Replace
the drive.
Circulation pump speed too low fault is registered (F67).
The check is carried out 10 sec. after the circulation pump has started.
1. Perform a circulation pump test as shown (F14, 1e,f,g,i, and j).
• If the circulation pump is good, replace the speed sensor (5.4.15.8).
Sensor softener fault is registered (F87).
If this fault is registered, an emergency program operates in which the reactivation
start time and the switching points for the EGS (electronically controlled water
softener) valve are given.
1. Check for approx. 9 VAC to the sensor softener 10N1 electronic module or the
data connection open-circuited.
2. Check the Sensor softener electronic module conductivity measurement. If no
connection faults exist, replace the water inlet mixer.
Turbidity sensor fault is registered (F88).
If this fault is registered, the program continues with default settings.
1. Check connections to electronic board and the turbidity sensor B3/10 and
perform a continuity check.
2. Check the turbidity sensor for correct function. Replace the spray arm feed pipe
with turbidity sensor if necessary
3. Check for foreign objects in the measurement path. Remove blockage or replace
feed pipe if it is necessary.
Load size registration inactive (F91)
If this fault is registered, the water intake block will operate by taking in the default
water quantity. In the subsequent additional fill, the quantity of which will normally
depend on the size of the load, will be replaced by a water intake block with fixed
water quantity.
1. Check the speed sensor for proper operation. See F53 Speed sensor
fault.
