Bosch SHX8PT55UC/05 dishwasher Parts

On Bosch dishwashers like model SHX8PT55UC, the most common service issue we see is a no-start or “won’t run” complaint caused by simple conditions such as the door not latching, the unit not being reset after a prior cycle, a delay start setting, or a power interruption. Use the SHX8PT55UC owner's manual self-help checks first.

Most common symptoms customers report

• Dishwasher does not start (display may be dark)
• Dishwasher seems to run a long time
• Unable to select a desired cycle (especially on hidden-control models)
• Buttons seem overly sensitive or do not respond

Quick checks that fix many “common problems”

These are the highest-impact items to verify before replacing parts:

• Latch the door firmly; if controls are hidden, open the door to change settings, then close it to run.
• Confirm the dishwasher is on, then select a cycle and press Start.
• Cancel/reset the cycle by pressing and holding Start for about 3 seconds.
• Check delay start; turn it off if you want an immediate start.
• Verify power at the breaker or fuse (a brief outage can stop a cycle).
• Make sure the water supply is on; a closed shutoff valve can prevent filling.

If it still won’t run: what to check next

If the basics above are good, these parts commonly relate to “won’t fill,” “won’t wash,” or “won’t drain” complaints:

Symptom	What it often points to	Example part for this model
Won’t fill or fills very slowly	Water inlet problem	Dishwasher water inlet valve 10023852
Poor cleaning, weak spray	Spray arm blockage or wear	Dishwasher spray arm, upper 00745856
Not draining	Drain path restriction or pump issue	Dishwasher drain pump 00620774

Why it matters

Most “common Bosch dishwasher problems” are actually start-up conditions (door, settings, reset, power, water supply). Checking those first prevents unnecessary part replacement and gets SHX8PT55UC running again faster.

To force a drain on your Bosch dishwasher model SHX8PT55UC, cancel the current cycle: press and hold Start for about 3 seconds until the display shows 0:01, then wait about 1 minute while the unit drains (steps are in the SHX8PT55UC owner's manual).

Quick steps to force a drain (cycle cancel)

• Press On/Off to wake the control (if needed).
• Press and hold Start for approximately 3 seconds.
• Keep holding until the display reads 0:01.
• Close the door and wait about 1 minute; you should hear the drain pump running.
• Open the door and press On/Off to turn the dishwasher off.

If it still will not drain

A forced drain will not clear a blockage or a failed drain component. These checks fix most “won’t drain” situations:

• Check the sink/disposer connection for a clog (especially right after a new disposer install).
• Make sure the drain hose is not kinked or crushed behind the dishwasher.
• Verify the drain hose routing is high-looped under the counter (prevents backflow).
• Clean the filter area in the tub bottom (food debris can restrict flow).
• If you hear humming but no water moves, the drain pump may be jammed or worn.

Parts that commonly affect draining

Symptom	Most likely area	Example part for SHX8PT55UC
No drain sound at all	Drain pump or control issue	Dishwasher drain pump 00620774
Slow drain, intermittent drain	Hose restriction or partial clog	Dishwasher drain hose 00744881

Why it matters

Forcing a drain is the fastest way to stop a cycle and clear standing water, but it also helps you diagnose the problem: if the unit drains during cancel, the pump and drain path are usually working, and the issue may be cycle-related or a temporary restriction.

We do not recommend running your Bosch SHX8PT55UC dishwasher with an E22 error showing. E22 is commonly tied to a drain or filter restriction; continuing to use the dishwasher can leave dirty water in the tub, reduce cleaning performance, and increase the chance of a no-drain condition.

What to do first (safe, quick checks)

• Turn the dishwasher off, then disconnect power at the breaker before reaching into the sump area.
• Remove and clean the filter system as shown in the SHX8PT55UC owner's manual.
• Check for standing water in the bottom; sponge it out so you can inspect the pump area.
• Inspect the waste water pump area for debris (glass, labels, food) and reinstall the pump cover securely.
• Reinstall filters and run a short cycle to confirm the unit drains normally.

Parts that commonly relate to E22 symptoms

If cleaning the filters and pump area does not restore normal draining, these model-compatible parts are common next suspects:

Symptom you notice	Most likely area	Example part for SHX8PT55UC
Water remains in tub after cycle	Drain path or drain pump	Dishwasher drain pump 00620774
Slow drain, gurgling, or backflow	Drain hose routing or blockage	Dishwasher drain hose 00744881
Poor wash plus intermittent drain issues	Sump area restriction	Dishwasher sump 00668102

Why it matters

Your dishwasher relies on a clear filter and an unobstructed waste water pump to move food soil and water out of the tub. When debris bypasses the filters, it can block the pump and trigger drain-related faults, which leads to poor cleaning and water left behind.

When to stop and schedule service

• The dishwasher will not drain at all after filter and pump checks
• You hear the drain pump humming but no water moves
• The error returns immediately after restarting

Yes. Most Bosch built-in dishwashers, including the Bosch SHX8PT55UC, are designed to fit standard residential kitchen cabinetry; the installation opening is typically about 24 inches wide, with a height around 34 inches and standard depth/clearance requirements. See the installation guide for the exact cutout and clearance specs.

What “standard size” means for SHX8PT55UC

Bosch built-in models are made to slide into a standard dishwasher enclosure so the door aligns with surrounding cabinets and the unit can be secured properly.

Typical built-in dishwasher fit targets:

• Width: about 24 inches (common U.S. standard)
• Height: about 34 inches (adjustable with leveling legs)
• Depth: designed for standard countertop and cabinet depth
• Clearance: extra space may be needed if installed in a corner so the door can open fully

Model-specific opening dimensions (from the install guide)

The SHX8PT55UC installation guide shows these key enclosure targets:

Measurement	What to plan for	Why it matters
Opening width	23 5/8 to 24 1/4 in. (600 to 616 mm)	Ensures the tub fits without binding
Opening height	Minimum about 33 7/8 in. (860 mm)	Allows the dishwasher to slide in and level
Corner clearance	Allow door swing clearance	Prevents the door from hitting a wall/cabinet

Quick checks before you buy or install

• Measure the cabinet opening width at the front and back (openings can be out of square).
• Confirm the countertop height and that the dishwasher can be leveled.
• If installing near a wall, verify door clearance for full opening.
• Plan routing for the water line and drain hose near the sink.

Why it matters

A “standard size” dishwasher still needs the right cutout and clearances; even a small mismatch can cause rubbing, poor door alignment, or difficulty anchoring the unit.

If you need installation hardware or replacement items while fitting the unit, you can order model-compatible parts from the list for SHX8PT55UC on this page, or search by model at Sears PartsDirect.
