Bosch SHX878WD5N/10 dishwasher Parts

A Bosch dishwasher like model SHX878WD5N typically lasts 10 to 15 years. Consistent cleaning, correct detergent use, and avoiding drain or fill problems help you reach the high end of that range and reduce premature pump or valve wear.

What affects lifespan most

• Water quality: hard water speeds up mineral buildup on the heater and internal passages
• Filter and sump cleanliness: clogs force the circulation system to work harder
• Drain performance: standing water strains the drain system and can cause odors
• Loading habits: blocked spray paths reduce cleaning and increase cycle stress
• Detergent and rinse aid use: too much detergent can leave residue; too little reduces cleaning

Maintenance checklist (best practices)

• Clean the filter area regularly and remove debris from the sump
• Run a dishwasher cleaner cycle periodically to reduce grease and scale
• Check the drain hose routing for kinks and ensure the high loop is maintained
• Keep spray arms clear of labels, seeds, and broken glass
• Address slow draining quickly; a failing pump can shorten overall dishwasher life

Parts that commonly impact longevity

If performance issues show up, these parts are frequent wear points on dishwashers and are available for this model:

Symptom	Likely system	Example model part
Won’t drain, water left in tub	Drain system	Dishwasher drain pump 00631200
Poor wash, weak spray	Wash circulation/heating	Dishwasher circulation pump with heater 12008381
Won’t fill or fills slowly	Water supply	Dishwasher water inlet valve 10023852

Why it matters

A dishwasher that is maintained and repaired early usually costs less to keep running and cleans better over its full service life. Catching drain, fill, or circulation problems early helps protect the motor, heater, and control components.

The most common problem we see with Bosch dishwashers like model SHX878WD5N is a drainage issue: water left in the tub at the end of the cycle. In most cases, the cause is a clogged filter area, a blocked drain path, or a failing drain component such as the dishwasher drain pump 00631200.

Most common symptoms (and what they usually mean)

• Standing water after the cycle: clogged filter/sump area, kinked drain hose, weak drain pump
• Slow draining or gurgling: partial blockage in the drain hose or sink/disposer connection
• Dishes not drying well: normal condensation drying behavior, rinse aid low, plastics holding water
• Stops mid-cycle: door not fully latched, drain problem triggering a safety stop, control issue
• Fills when it should not: inlet valve not sealing fully (less common)

Quick checks we recommend first

1. Turn off power at the breaker.
2. Remove and clean the filter area in the bottom of the tub; clear debris from the sump.
3. Inspect the drain hose routing for kinks, crushing, or a low loop problem.
4. Check the sink drain or garbage disposer inlet where the dishwasher hose connects for blockage.
5. Run a rinse cycle and listen for the drain pump at the end.

Parts that commonly fix “won’t drain” complaints

Symptom	Likely area	Example part for SHX878WD5N
Hums but won’t drain	Drain pump jammed or weak	Dishwasher drain pump 00631200
Leaks or poor drain flow	Drain hose restricted	Dishwasher drain hose (model-specific)
Intermittent drain issues	Pump cover not sealing	Dishwasher drain pump lid 00611322

Why it matters

When a Bosch dishwasher cannot drain correctly, it can leave dirty water in the sump, reduce cleaning performance, and trigger error conditions that stop the cycle. Fixing the drain path early also helps protect the circulation system and heater from running under poor water conditions.

Helpful DIY reference

• Use Bosch dishwasher error codes to match symptoms to the most likely drain, fill, or heating fault.

Yes, we typically see Bosch dishwasher E24 as a drain problem you can often fix yourself on model SHX878WD5N by clearing a blockage, correcting the drain hose routing, and checking the air gap or garbage disposal inlet. If the dishwasher still will not drain, a drain pump issue is the next common cause.

What E24 usually means on a Bosch dishwasher

E24 points to restricted draining. The dishwasher is trying to pump water out but cannot move it fast enough.

Common DIY causes:

• Clogged filter area or sump (food debris, labels, glass)
• Kinked, crushed, or improperly routed drain hose
• Blocked air gap (if your setup uses one)
• Garbage disposal inlet plug not removed (new disposal installs)
• Drain pump impeller jammed or pump failing

DIY checks to try first (in order)

• Turn off power at the breaker; then remove standing water with a cup or wet/dry vac.
• Clean the filter area and check the sump for debris.
• Inspect the drain hose for kinks and for a proper high loop under the counter.
• If you have an air gap, remove the cap and clear the air gap and hose.
• If draining into a disposal, confirm the disposal inlet is open and not clogged.

If the pump hums but does not move water, inspect the pump area for obstructions; if it is clear and E24 returns, replacing the pump is a common repair using the dishwasher drain pump 00631200.

Quick symptom-to-fix guide

What you notice	Most likely cause	Best next step
Water stays in tub, no pump sound	Power/control issue	Check breaker, door latch, then diagnostics using Bosch dishwasher error codes
Pump runs but drains slowly	Partial blockage	Clean filters, air gap, hose, disposal inlet
Loud buzzing/grinding during drain	Jammed pump	Clear debris; replace pump if noise continues
Drains sometimes, then E24 returns	Intermittent restriction	Recheck hose routing and air gap; inspect pump impeller

Why it matters

An E24 drain restriction can leave dirty water in the sump, cause odors, and trigger repeat error codes. Fixing the drain path early also helps protect the drain pump and reduces leak risk from overfilling.
