Bosch SHU43C07UC/14 dishwasher Parts

Most Bosch built-in dishwashers, including the Bosch SHU43C07UC, are designed to fit a standard 24-inch-wide undercounter opening. Bosch also makes compact 18-inch models, so the “standard size” depends on which series you own; confirm your exact cutout and hookup requirements in the SHU43C07UC installation guide.

What “standard size” means for fit

A dishwasher can be “standard” in width but still require the right cabinet opening, leveling range, and door clearance.

• Standard built-in width: typically about 24 inches
• Compact built-in width: typically about 18 inches
• Height and depth: vary by model and installation method (leveling legs, flooring thickness, countertop height)
• Door clearance: depends on toe-kick height and how the unit is leveled

Quick size comparison

Dishwasher type	Typical width	Common install location
Full-size built-in	~24 in.	Undercounter cabinet opening
Compact built-in	~18 in.	Smaller kitchens, bar areas
Portable/freestanding	varies	Rolls to sink or sits in place

How to confirm your opening is correct

Use these checks before ordering parts or planning an install.

• Verify the model and installation requirements in the SHU43C07UC installation guide.
• Measure the cabinet opening width at the front and back (openings can taper).
• Confirm you have space for the door to open fully without hitting adjacent cabinets.
• Check that the water supply, drain, and power locations match the install requirements.
• Leveling matters; an unlevel dishwasher can affect door closing and can contribute to leaks.

Why it matters

A “standard size” dishwasher can still install poorly if the opening is tight, the floor is uneven, or the unit is not anchored and leveled correctly. Correct fit helps the door latch reliably, reduces vibration, and supports proper draining and drying performance.

On Bosch dishwashers like model SHU43C07UC, the most common service issue we see is a heating-related problem that leads to poor drying, lukewarm wash water, or unusually long cycle times. Start by checking cycle options and basic maintenance steps in the SHU43C07UC owner’s manual.

What “heating problem” usually looks like

When the dishwasher is not heating as expected, customers typically notice one or more of these symptoms:

• Cycles seem to run much longer than normal
• Dishes come out wet or cool (condensation drying is less effective)
• The unit finishes, but results are inconsistent from load to load
• The “Sanitized” light does not illuminate after an NSF-certified cycle
• The dishwasher appears to pause during the wash while it tries to reach temperature

Why the “Sanitized” light can be a clue

Your Bosch dishwasher is NSF Certified, and certain cycles are designed to meet strict time and temperature requirements. If household water is too hot, the dishwasher may reduce heating time and the “Sanitized” light may not illuminate, even when the cycle completes.

Quick checks we recommend before replacing parts

These steps solve a large share of “no heat” and “long cycle” complaints without guessing at parts:

• Run hot water at the sink until it is hot, then start the dishwasher
• Use an NSF-certified cycle (Power Scrub Plus, Scrub Wash, Regular Wash, or Delicate/Economy Wash)
• Confirm rinse aid is being used (it supports Bosch condensation drying)
• Clean and maintain key areas (spray arms, filters, door seals)
• Crack the door open for a few minutes after the cycle to speed cooling and drying

Parts that are commonly involved (when symptoms point to them)

If troubleshooting points to a fill, leak, or water-level issue that can affect heating performance, these model-matched parts are common suspects:

Symptom	What to inspect	Model-matched part example
Not filling or fills slowly	Water inlet path and valve operation	Valve 00425458
Overfilling or won’t stop filling	Float movement and switch function	Dishwasher float switch 00165256
Leaks at the door	Door sealing surfaces and gasket condition	Door seal 00432490

Why it matters

Bosch dishwashers rely on correct water temperature and proper water level for wash performance, sanitization cycles, and effective condensation drying. When heating is disrupted, you often see longer cycles, weaker cleaning, and wetter dishes.

Bosch dishwasher error 14 (often shown as E14) typically points to a water fill or flow-measurement problem. On the Bosch SHU43C07UC, start by resetting the cycle, then check for proper water supply and inspect the flow meter area and inlet components per the SHU43C07UC owner’s manual.

What to do first (fast checks)

• Turn the dishwasher off, then back on; try Cancel/Drain to clear a stuck cycle.
• Confirm the water shutoff valve under the sink is fully open.
• Make sure the inlet hose is not kinked or crushed behind the unit.
• Check that the dishwasher door closes and latches firmly.
• If the tub is overfilled or you see water in the base, let it dry out before restarting.

Likely causes and the most common fixes

E14 is commonly tied to the dishwasher not sensing the correct amount of incoming water. These are the usual culprits:

• Restricted water supply: low pressure, partially closed shutoff, or a clogged inlet screen.
• Flow meter or inlet side chamber issue: debris buildup or a sensor that is not seated correctly.
• Inlet valve problem: the valve may not open consistently or may be restricted.

If you suspect the inlet valve, the model-specific replacement is the valve 00425458.

Quick troubleshooting table

What you notice	What it usually means	What we recommend
Dishwasher fills very slowly	Restricted supply or clogged inlet screen	Verify shutoff is open; inspect hose and inlet screen
Fills then stops with E14	Flow measurement not reading correctly	Inspect flow meter area for debris; reseat connections
No fill sound at all	Valve not opening or no water supply	Confirm supply; test/replace inlet valve

Why it matters

When the dishwasher cannot accurately measure incoming water, it can stop the cycle to prevent poor cleaning, overheating, or overflow. Fixing the fill and sensing issue restores normal wash performance and helps protect internal components.

To force a drain on your Bosch dishwasher model SHU43C07UC, cancel the current cycle using the Cancel Drain button combination; the dishwasher will run the drain pump as part of that cancel routine. For safety, wait at least 10 seconds after opening the door during a wash or rinse.

How to start Cancel Drain (forces a drain)

Use the steps that match your control style; both methods trigger the Cancel Drain function described in the SHU43C07UC user manual.

• Front control models: Press and hold for 3 seconds the two buttons marked with dots and labeled Cancel Drain.
• Top control models:
  • Open the door just enough to access the controls.
  • Press and hold for 3 seconds the two buttons marked with dots and labeled Cancel Drain.
  • Close the door to let the dishwasher drain.

If it still will not drain

A forced drain will not clear a physical blockage or a drain path problem. Check these common causes first:

• Air gap or sink drain connection: Clear debris in the air gap (if installed) and confirm the sink/disposer inlet is not clogged.
• Drain hose routing: Make sure the hose is not kinked, crushed, or sagging; a high loop helps prevent backflow.
• Filter and sump area: Clean the filter and remove any large objects that can block the pump intake.
• Drain hose condition: If the hose is split, soft, or restricted internally, replace the drain hose 00263099.
• Overfill protection: If the float is stuck up, the unit may behave abnormally; inspect the float area and consider the dishwasher float switch 00165256 if the switch is failing.

Quick checks: symptoms and what they usually mean

What you notice	What to check first	Common fix
Hums but no water leaves	Filter/sump blockage	Clean filter, remove debris
Drains slowly	Kinked hose or partial clog	Re-route hose, clear clog
Water returns to tub	No high loop or clogged air gap	Correct routing, clean air gap
No drain sound at all	Cancel Drain not started or door not closed	Re-run Cancel Drain, close door

Why it matters

Standing water can cause odors, poor cleaning, and leaks around the door area. Using Cancel Drain correctly helps protect the pump and gets the dishwasher ready to restart a cycle.

For step-by-step control instructions and safety notes (including the 10-second wait before fully opening the door during a wash/rinse), follow the SHU43C07UC user manual.
