Bosch SHE55R52UC/64 dishwasher Parts

On a Bosch dishwasher like model SHE55R52UC, an E22 error typically points to a drainage restriction (most often a dirty filter area). We recommend not running more cycles until you clear the blockage; continuing to run it can leave dirty water in the tub and strain the drain system.

What to do first (safe, quick checks)

• Cancel the cycle and let the unit drain if it will.
• Turn off power at the breaker before reaching into the sump area.
• Remove and clean the filter area; rinse debris off thoroughly.
• Check the drain hose routing for kinks or a clogged high loop/air gap.
• If the dishwasher recently sat unused for weeks, run hot water at a nearby faucet first (helps purge any gas and ensures hot water supply is ready).
• Restore power and run a short rinse to confirm normal draining.

Common causes and likely fixes

What you notice	Most likely cause	What usually fixes it
Water left in bottom, dishes not clean	Filter/sump blockage	Clean filter and sump area per the SHE55R52UC user manual
Hums but won’t drain	Drain pump obstruction or failure	Inspect for debris; replace pump if needed (see drain pump 00642239)
Slow drain or intermittent E22	Partially clogged hose	Clear/replace hose (see dishwasher drain hose 00668108)
E22 after filling issues	Poor drain leading to overfill protection	Verify drain path; check float system if symptoms persist

Why it matters

E22 is a “stop and clear the drain path” type of error. Fixing the restriction first prevents standing water, odor, poor wash results, and unnecessary wear on the drain pump and recirculation system.

When to stop and schedule service

• You cleaned the filter and confirmed the hose is clear, but E22 returns immediately.
• The dishwasher will not drain at all and you hear abnormal grinding from the pump.
• You see leaking during drain; address leaks before continued use.

The most common Bosch dishwasher issue we see on models like the Bosch SHE55R52UC is poor cleaning or a drain problem caused by restricted water flow. In most cases, cleaning the filters, clearing the drain path, and confirming proper fill fixes the root cause without major repairs.

Quick checks that fix most complaints

• Clean the filter area and remove food debris (this is the top cause of weak wash and standing water).
• Make sure spray arms spin freely and the holes are not plugged.
• Confirm the sink drain and garbage disposal inlet are clear (new disposals often have a knockout plug).
• Check the drain hose routing for kinks and make sure it has a high loop.
• Run hot water at the sink before starting a cycle to improve wash performance.

Common symptoms and the most likely causes

Symptom	Most common cause	What to check first
Dishes not clean	Clogged filters or spray arm blockage	Filter cleaning, spray arm holes
Water left in tub	Drain restriction or weak drain pump	Filter area, hose routing
Not filling well	Water supply issue or inlet valve problem	Shutoff valve, inlet screen
Overfilling or odd fill behavior	Float/float switch issue	Float movement, debris under float

Parts that often solve the underlying problem

If cleaning and hose checks do not correct the issue, these model-matched parts are common fixes:

• Sump filter 00441905 (restricted filtration can reduce circulation and cleaning)
• Drain pump 00642239 (when the unit hums but drains slowly or not at all)
• Dishwasher water inlet valve 00622058 (when fill is weak or intermittent)
• Dishwasher float switch 00165256 (when fill level sensing is unreliable)

Why it matters

A dishwasher that cannot circulate or drain correctly will re-deposit soil, leave cloudy glassware, and can trigger longer cycle times. Keeping the filtration and drain path clear protects the recirculation pump and helps the dishwasher run at full wash pressure.

Where to confirm model-specific steps

If you’re shopping for a dishwasher, we recommend staying away from any model line with a consistent pattern of service issues in the areas that matter most: leaking, poor draining, weak cleaning, and repeated electronic failures. For your Bosch dishwasher model SHE55R52UC, the best “avoid” strategy is choosing based on reliability signals and supportability, not just brand name.

What to avoid (practical red flags)

• Models with frequent leak complaints (door seal, sump, or hose routing issues)
• Units that commonly fail to drain or leave standing water
• Dishwashers with repeated control or user interface failures
• Designs that are hard to service (limited parts availability, complex assemblies)
• Poor drying performance if you rely on plastics drying well

Quick checklist before you buy

Use this list to screen any dishwasher model, including Bosch, Whirlpool, GE, KitchenAid, LG, Samsung, Frigidaire, and others:

• Parts support: common parts like pumps, valves, and seals are readily available
• Installation requirements: drain hose routing and anchoring are straightforward
• Noise and cycle time: acceptable for your household routine
• Error code clarity: the brand provides clear diagnostics
• Local service: qualified technicians are available in your area

Why installation details matter more than most people think

A dishwasher that is installed incorrectly can look like a “bad model.” For example, Bosch installation guidance calls for the drain hose to be routed with a high loop (a portion at least 20 inches off the cabinet floor) to help prevent draining problems. Following the installation guide helps prevent avoidable issues that get blamed on the dishwasher.

Common “bad dishwasher” symptoms that are often fixable

Symptom	Often caused by	Typical fix area
Won’t fill	Water supply issue or inlet valve problem	Water inlet system
Won’t drain	Hose routing, clog, or drain pump issue	Drain path
Leaks	Door seal wear or loose connections	Door and plumbing
Poor cleaning	Filter/sump restriction or weak circulation	Filtration and wash system

Helpful model-specific resources

• For decoding reliability-related faults (drain, fill, heating), use Bosch dishwasher error codes.
• If your SHE55R52UC is not filling and you’re troubleshooting parts, the dishwasher water inlet valve 00622058 is a common component in the fill circuit.

Why it matters

“Avoid” lists are usually based on patterns: water handling problems (fill, drain, leaks) and electronics. Screening for those failure categories, plus correct installation and strong parts support, leads to a better long-term ownership experience than choosing purely by brand reputation.
