Question 1

the sanitize light never comes on after a cycle, even on the sanitize setting. is it broken?

Accepted Answer

DIAGNOSIS The sanitize indicator requires the final rinse water to reach 150°F and maintain it for a specific time. Failure indicates insufficient hot water supply. FIX Ensure your household water heater is set to at least 120°F. Run the hot water at the sink next to the dishwasher until it is fully hot before starting a cycle. Use a cycle with a sanitize option (Heavy, Normal, Auto) and ensure the sanitize button is selected. IF THAT DIDN'T WORK The internal heating element or its thermostat may be faulty, preventing the unit from achieving the required final rinse temperature. HEADS UP The sanitize light is an indicator, not a washer setting. The cycle will run without it, but the NSF certification requires that temperature to be met for the light to illuminate.

Question 2

the third rack on top keeps falling down when i pull out the lower rack, it's super annoying.

Accepted Answer

DIAGNOSIS The MyWay third rack is not correctly locked into its upper glide position. The rack detents are not fully engaged. FIX Remove the third rack completely. Inspect the four glide sockets on the side walls. Ensure no debris is in the sockets. Re-insert the rack, pushing it all the way back until you hear/feel a definitive click on both sides. The rack should now be secure. IF THAT DIDN'T WORK The glide sockets or the rack's glide arms may be damaged or worn. Contact Bosch for replacement parts for the third rack glide system. HEADS UP When loading the third rack, distribute weight evenly. Heavy items placed on the front of the rack can create a lever effect, dislodging it.

Question 3

i keep getting an e24 error code on my bosch dishwasher, what does that mean and how do i clear it?

Accepted Answer

DIAGNOSIS E24 indicates a water intake fault. The dishwasher did not fill with the required amount of water within the expected time. FIX Check your water supply. Ensure the sink's hot water valve under the sink is fully open. Inspect the inlet hose for kinks. Disconnect the fill hose from the valve and check the mesh filter for debris; clean it if clogged. Restart the dishwasher. IF THAT DIDN'T WORK The water inlet valve solenoid may be faulty. Test the valve for continuity with a multimeter. A failed valve will not open to allow water in. HEADS UP Always use the error code readout. To view stored errors, press any program button for 3 seconds. The most recent error (like E24) will display.

Question 4

the control panel on my bosch 800 is totally dead, no lights, no response, but i can hear a faint hum inside.

Accepted Answer

DIAGNOSIS A dead control panel with internal power suggests a failed control panel unit or a loose internal connector, not a total power loss. FIX First, confirm power at the outlet. Next, perform a hard reset. Turn off the circuit breaker for the dishwasher for five minutes. Restore power. If the panel remains dead, the issue is internal. The main control board may still be sending power, but the UI (User Interface) board is dead. IF THAT DIDN'T WORK The wiring harness connecting the main board to the control panel may be disconnected or damaged. This requires removing the door panel to inspect. HEADS UP The faint hum is likely the control board receiving power. Do not attempt to remove the door panel without first disconnecting power at the breaker.

Question 5

dishes are coming out wet and not dry even on the extra dry setting, this bosch 800 has crystaldry.

Accepted Answer

DIAGNOSIS The CrystalDry zeolite drying system is not activating. This is often due to a blocked vent path, a failed fan, or incorrect cycle selection. FIX Ensure you are using a cycle that activates CrystalDry (Auto, Heavy, Normal, Speed60). Check the vent on the inside of the door. It must be clear of large utensils or dishware blocking airflow. Run a diagnostic test: press Start three times rapidly. Listen for the fan motor during the drying phase. IF THAT DIDN'T WORK The zeolite container's vent flap may be stuck. Or the fan motor for the drying circuit may have failed, requiring a service call. HEADS UP Plastic items and certain glazes will not get hot enough for perfect drying, even with CrystalDry. Use the Extra Dry button and position plastic on the top rack.

Question 6

dishwasher is making a loud grinding or rattling noise during the wash cycle, sounds like it's coming from the bottom.

Accepted Answer

DIAGNOSIS A foreign object is caught in the wash pump or spray arm. Common culprits are lemon pits, olive pits, or broken glass. FIX Immediately cancel the cycle. Remove the lower rack and filter assembly (the microfilter and flat filter). Visually inspect the sump area for debris. Remove the silverware basket and check the small wash arm for obstructions. Manually rotate the lower spray arm to feel for grinding. IF THAT DIDN'T WORK The wash pump impeller may be damaged by the object. If noise persists after clearing debris, the circulation pump may need replacement. HEADS UP Always use the extra fine filter (supplied) in the silverware basket to prevent small hard items from falling into the sump.

Question 7

water stays in the bottom of my bosch shpm88z75n after a cycle, it's not draining fully.

Accepted Answer

DIAGNOSIS Standing water indicates a drain pump failure, a clog, or a faulty check valve in the drain hose. FIX Check the drain hose for kinks or clogs first. Disconnect the hose from the sink drain or garbage disposal and blow through it. Next, inspect the drain pump. Remove the lower kick plate and filter assembly. Manually check the pump impeller for debris (glass, pits). Clear any obstruction. IF THAT DIDN'T WORK The drain pump motor itself may have failed. Listen for a humming sound during a drain cycle. No sound points to a dead pump motor. Replace the drain pump assembly. HEADS UP Bosch models use a float switch in the sump. Ensure this switch moves freely and is not jammed by debris, which can also prevent draining.

Question 8

my bosch 800 series dishwasher just shows three dashes "---" on the display and won't start, what's wrong?

Accepted Answer

DIAGNOSIS The display shows "---" when the door latch or door switch has failed. This is a safety interlock error. FIX First, power cycle the unit. Turn off the circuit breaker for one minute. Restore power. If "---" persists, the door latch assembly is faulty. Remove the inner door panel to inspect the microswitch on the latch. Test for continuity. Replace the entire door latch assembly (part number 00611913 is common). IF THAT DIDN'T WORK The main control board may have a fault. Check for any visible damage or burnt components on the board. A board replacement is the next step. HEADS UP The door latch assembly includes the striker. Ensure the new striker aligns perfectly with the door catch.
