Safety first — lockout / tagout

Cut power at the breaker before tilting the dishwasher. Shut off the water supply under the sink.

Tools you'll need

  • Towels
  • Flashlight
  • Vinegar
  • Bosch test strip (for hardness)

Step-by-step repair flows

Pick the symptom that matches what your Bosch SHPM88Z75N is doing right now. Each flow ends in a parts list and an option to escalate if it's beyond comfortable DIY scope.

Symptom

E15 error — water in the leak tray

The Aquastop tray senses any drop of water on the cabinet floor and locks the inlet valve. Often a one-time spill — not a hardware failure.

Diagnostic flow

  1. 1

    Power off and tilt

    Disconnect power. Tilt the dishwasher backward 45° and hold for 60 seconds — water in the tray runs to the rear and trips the float reset.

  2. 2

    Towel the cabinet floor

    Slide a towel under the unit and let any residual water wick out before restoring power.

  3. 3

    Restore and test

    Stand the unit upright, plug in, run Rinse. If E15 returns within minutes, you have an actual leak — inspect the door gasket and sump.

  4. 4

    Inspect for slow leaks

    Most common: hairline crack in the heat-pump body or a torn sump gasket. Replace the affected part.

Recommended parts

  • Sump gasket 00754869

    $20–$35

  • Heat pump 12014090

    Only if cracked body confirmed

    $220–$320

Symptom

Cloudy or filmy glasses

Bosch dispensers are precision-calibrated. Wrong water-hardness setting or empty rinse-aid is the cause 95% of the time.

Diagnostic flow

  1. 1

    Test your water hardness

    Use a $5 test strip from the hardware store. Bosch settings: H:00–H:07 depending on grains per gallon.

  2. 2

    Adjust the dishwasher's hardness setting

    With door open, hold Power Scrub Plus + On for 3 sec — the display enters program mode; cycle to H:xx and select.

  3. 3

    Refill the rinse-aid reservoir

    Adjacent to the detergent cup. Cloudy etching = mineral; spotting = rinse-aid empty.

  4. 4

    Vinegar rinse

    Run an empty Auto cycle with 2 cups of white vinegar in a top-rack cup. Strips existing buildup.

Recommended parts

  • Bosch rinse aid (Finish JetDry compatible)

    $5–$10

Bosch SHPM88Z75N — FAQ

How do I clear E15 on a Bosch dishwasher?
Tilt the unit back 45° for 60 seconds to drain the leak tray, then power-cycle. If E15 returns within minutes, there's an active leak — inspect the sump gasket.
Why do my glasses come out cloudy in my Bosch SHPM88Z75N?
Wrong water-hardness setting or empty rinse-aid. Test your water, set the dishwasher's H-level, and keep the rinse-aid reservoir full.
