6.16 Replacing power modules

Required tools:
Phillips screwdriver PH2
Slotted screwdriver Blade 4 mm x 0.8 mm x 100 mm, only
China
The power module can be accessed from the right side of the dishwasher after pulling
it out.
Before replacing power modules:
¡ Check error codes before replacing power modules. Many good power mod-
ules have been replaced and faulty parts not replaced, causing repeat calls.
¡ 75% of modules returned for analysis have checked out OK. Most issues are
due to loose connections and error codes for other parts.
Technicians occasionally ask to identify power modules from 10-digit material #'s,
which cannot be done:
¡ Due to iService, programmed power module part #'s cannot be identified from 10-
digit material #'s.
¡ 10-digit material #'s are linked to unprogrammed power modules, used for dozens
of programmed modules.
¡
Power module part #'s cannot be identified without model, KI and FD #'s from
serial labels.
Prerequisite:
Customer service error code program has been run.
Error codes have been recorded.
