    Default SHU3322uc starting to clean poorly

    Model Number: SHU3322US/U12
    Brand: Bosch
    Age: More than 10 years

    Hi, we've got a Bosch "DLX series" SHU3322 that has always worked more or less fine. It was here when we bought the house, not sure how old it really is.

    We've had several days lately where about half the dishes are not clean after a cycle. No other changes in detergent, loading procedures, etc.

    I ran the test cycle, and at the end both the regular wash and rinse/hold lights were FLASHING. Not sure if that's "lit" as described in the various instructions I've found, or if flashing is a different indication than just lit.

    Any insight into the meaning of that test is appreciated, as well as other things to check for overall poor performance before we start shopping for a replacement!

    Thanks.

    Hi,

    A copy:

    WASHABILITY
    There are four factors that play a critical role in Washability: Time, Temperature, Water and Detergent. It is important when attempting to determine the cause of a Washability complaint that all four factors be
    considered and tested.

    Time: The duration of the program is accurate.
    Temperature: The wash and rinse temperatures are within the desired range.
    Water: The unit is filling with the correct amount of water
    Detergent: The detergent is fresh, and not being used in excessive amounts.
    Please note: Other factors such as clean filters, a properly routed drain hose, water hardness and quality, as well as loading of items will also effect Washability.

    Thanks Jeff.

    So, with the two flashing lights, am I looking at a water sensor and a heating error? Two out of 4 is not so good - I'm trying to figure out when it's worth a replacement.

    thanks!!!

    To start test program, press and hold both POWER SCRUB PLUS and RINSE & HOLD program buttons, then turn unit on by pressing ON/OFF button. When program buttons are released, lights above them will flash. To end test program, press ON/OFF button.
    To check program indicator lights (POWER SCRUB PLUS, REGULAR WASH and RINSE & HOLD), press and hold each program button. When REGULAR WASH program button is pressed, CLEAN light also comes on.
    To start testing, press both POWER SCRUB PLUS and RINSE & HOLD buttons a second time. When testing has ended and a fault was detected, the following indicator lights will be lit:
    POWER SCRUB PLUS = Heater fault
    REGULAR WASH = Water filling fault (over or under filling)
    RINSE & HOLD = NTC (temperature sensor) fault note circulation motor stops shortly after it started during an NTC fault
    To check for heater, high limit or flow switch problems, start testing until heating starts. Using a meter with a current coil, measure current going into dishwasher. If current is ~ 11 A, then heater, high limit and flow switch are OK. If current stays at ~ 1.5-2 A, then heater, high limit or flow switch are faulty.
    If water level switch (f1) has failed (opened), REGULAR WASH light will come on and unit will continually fill and drain where testing won't be completed. If flow switch (e5) has failed (opened), water won't heat (to 150F) and water wont stop circulating. If NTC probe (f2/f4) has failed (opened), RINSE & HOLD light will come on immediately and testing will end shortly after water has started circulating.
    If more than one fault occurs, more than one light will be lit.

    *****
    Sounds more like the light will come on and stay on when a problem has occured....esp for a washability problem I'd check other things first before going into the test program.
