Bosch SHX43P15UC/59 dishwasher Parts

Yes. Bosch dishwashers like model SHX43P15UC are built to fit a standard 24-inch dishwasher opening in most kitchens. For this model, the installation guide calls for an enclosure opening at least 34 inches high and 23 5/8 inches (60 to 61 cm) wide. See the installation guide for the full cutout and hookup requirements.

Standard size: what it means for your cabinet opening

Most built-in 24-inch dishwashers are designed around common cabinet cutouts. For SHX43P15UC, confirm these basics before you slide the unit in:

• Opening height: at least 34 inches (87 cm)
• Opening width: 23 5/8 inches (60 to 61 cm)
• Drain hose routing: keep a high loop at least 20 inches (51 cm) above the floor
• Drain hose length: does not exceed 92 inches (234 cm)
• Water supply: flush hot water at the sink for at least 2 minutes before connecting

Quick fit check table

What to measure	Typical expectation	SHX43P15UC guidance
Cabinet opening width	24-inch class opening	23 5/8 in (60 to 61 cm) minimum opening width
Cabinet opening height	34 inches or more	34 in (87 cm) minimum opening height
Drain hose setup	High loop required	Raise a portion at least 20 in (51 cm) above floor

Why it matters

A dishwasher that is even slightly tight in the opening can bind against the cabinets, make leveling difficult, and increase the chance of leaks at the door seal or hose connections. Verifying the cutout and hose routing up front helps the dishwasher install square and drain correctly.

The most common Bosch dishwasher issue is a drain-related problem: water left in the tub because the filter area or drain path is restricted. On Bosch model SHX43P15UC, this often ties back to food debris buildup, an obstructed drain hose, or a drain system component that is not moving water out.

Quick checks we recommend first

• Cancel the cycle and let the dishwasher attempt to drain.
• Remove and clean the filter area; clear any food debris from the sump.
• Check for standing water and remove it so you can see the drain inlet clearly.
• Inspect the drain hose routing for kinks or a pinch behind the unit.
• Confirm the sink drain or disposer inlet (where the dishwasher connects) is not blocked.
• If you see suds, switch to the correct dishwasher detergent and run a rinse cycle.

What the symptoms usually point to

Symptom	Most likely cause	Common next step
Water remains in bottom after cycle	Obstructed drain path or hose	Clean filter area; inspect hose
Odor plus residual water	Food debris in tub or near door seal; poor draining	Clean tub, filter area, and door seal
Leaks during/after wash	Suds, door seal out of track, blocked vent, or installation issue	Reduce suds; reseat seal; check vent

Parts that commonly solve drain complaints

If cleaning and hose checks do not restore normal draining, these model-matched parts are the most common fixes:

• Drain pump 00642239 (pumps water out during drain)
• Dishwasher drain hose 00668108 (replaces a restricted, kinked, or leaking hose)
• Sump filter 00441905 (restores proper flow through the filtration area)

Why it matters

A dishwasher that does not drain fully can cause odor, poor cleaning, and longer run times because the unit cannot circulate and evacuate water correctly. Keeping the filter area clean and the drain path clear prevents repeat problems.

To force-drain your Bosch dishwasher model SHX43P15UC, cancel the cycle so the unit runs its drain routine, then clear the filter area so water can reach the drain pump. Use the cancel/reset steps in the owner's manual and remove standing water safely before checking the pump area.

Fast ways to force a drain

1) Cancel the cycle (most effective)

Use the control-panel cancel/reset function to end the wash and trigger draining.

• Open the door carefully; wait for water noises to stop to avoid hot-water splash
• Press ON/OFF to stop the cycle
• Wait at least 10 seconds
• Turn the dishwasher back ON/OFF as directed and close the door to resume the drain routine

2) Clear the filter system so it can drain

A clogged filter area can trap water in the sump.

• Pull out the lower rack
• Remove the filter assembly (large object trap/cylinder filter)
• Rinse the cylinder filter under running water
• Lift and rinse the fine filter and micro filter
• Reinstall and lock the filter assembly (ring handle turns about 1/4 turn until locked)

If water is still standing in the tub

If the dishwasher will not drain after canceling and cleaning filters, focus on the drain path.

• Check for a kinked or obstructed drain hose
• Look for food debris around the sump inlet
• If the pump hums but does not move water, the drain pump can be the failure point

Common drain-related parts for this model

What you’re checking	What it affects	Model-matched part
Drain pump not pumping	Water stays in tub	Drain pump 00642239
Drain hose blocked/kinked	Slow or no drain	Dishwasher drain hose 00668108
Filter system clogged	Poor flow to pump	Sump filter 00441905

Why it matters

Standing water causes odor, can redeposit soil on dishes, and can lead to leak symptoms if the tub overfills on the next fill. Restoring normal drain flow protects the wash system and helps cycles finish correctly.

On a Bosch SHX43P15UC dishwasher, the E15 error means water collected in the base pan under the tub and lifted the leak-protection float. The leak is usually a slow drip from the door sealing area, a hose connection, or the sump and pump area that runs down into the bottom tray.

Most common leak locations to check

Turn off power at the breaker before inspecting.

• Door sealing surfaces: debris, misalignment, or a seal pulled out of its track
• Suds overflow: wrong detergent creates foam that escapes the tub
• Drain path: loose or cracked drain hose, or a drain pump seep during drain
• Fill system: inlet valve or fill connection dripping early in the cycle
• Sump and pumps: seep around the sump filter area, recirculation pump, or drain pump

Quick isolation steps

Use timing to pinpoint the source.

1. Start a short cycle and note when the first water appears (fill, wash, or drain).
2. Check for suds; correct detergent use and clear suds before retesting.
3. Inspect and reseat the door seal; clean the sealing surfaces.
4. Look for wetness, mineral tracks, or staining on hoses and clamps.
5. Press Cancel/Reset to drain, then re-check underneath for fresh drips.

Parts that commonly fix the underlying leak

Match what you see to the likely area.

What you observe	Likely source	Part to consider
Water at bottom/front corners	Door sealing	Door seal 00432490
Leak during drain	Drain hose or drain pump	Dishwasher drain hose 00668108 or drain pump 00642239
Leak during wash circulation	Recirculation system	Dishwasher recirculation pump assembly 00442548

Why it matters

E15 is a protection response; stopping the leak at the exact drip point prevents repeat shutdowns and helps you replace only the part that is actually leaking.
