Bosch SHE43RL5UC/64 dishwasher Parts

The most common Bosch dishwasher issue we see is a wash or heat problem caused by a failed heating circuit or control, which can leave dishes wet, extend cycle time, or stop the unit mid-cycle. For Bosch model SHE43RL5UC, start by checking for error codes and basic water, drain, and door-latch conditions in the owner's manual.

What “most common” usually looks like

These symptoms show up most often on Bosch dishwashers when heating, sensing, or control functions are not working correctly:

• Cycle runs much longer than normal or seems to run “forever”
• Dishes come out cool and wet, especially plastics
• Detergent does not dissolve well, or there is gritty residue
• Unit stops mid-cycle and beeps or shows an error
• Water is present but wash performance is weak (poor spray action)

A fast next step is to match any displayed code to the troubleshooting chart in Bosch dishwasher error codes.

Quick checks before replacing parts

We recommend these checks first because they solve a large share of “no heat” and “poor wash” complaints without parts:

• Confirm hot water supply is on and the sink faucet runs hot before starting a cycle
• Clean the filter and check for debris that restricts circulation (common on low-cleaning complaints)
• Verify the door closes and latches firmly; a door switch issue can interrupt heating and washing
• Make sure the unit is draining fully; standing water can trigger abnormal cycle behavior
• Reset power (turn off breaker for 1 minute, then restore) and re-test

Parts that commonly relate to these symptoms (SHE43RL5UC)

If troubleshooting points to a component failure, these parts on this model are frequent suspects:

Symptom	Common cause	Part to check on this model
Long cycle, poor drying, water not hot	Control or heating circuit issue	Dishwasher electronic control board 00705665
Weak cleaning, odd wash noises	Circulation problem	Dishwasher circulation pump 00442548
Not filling or fills slowly	Water supply control issue	Dishwasher water inlet valve 00622058
Stops because of overfill protection	Float stuck or switch issue	Dishwasher float assembly 00165301

For ordering, use the parts list for SHE43RL5UC on this page, or search by model at Sears PartsDirect.

Why it matters

Bosch dishwashers rely on correct water temperature and strong circulation to clean and dry properly. When heating or control functions fail, the dishwasher can compensate by extending the cycle, which looks like a “run forever” problem and often leads to poor results.

A Bosch dishwasher typically lasts 10 to 15 years with normal household use and basic maintenance. For your Bosch SHE43RL5UC, keeping the filter and drain path clean and fixing small leaks early helps you reach the high end of that range; see the owner's manual for care guidance.

Typical lifespan and what affects it

Most dishwashers wear out from heat, moisture, and pump or seal wear. These factors have the biggest impact:

• Water quality (hard water speeds mineral buildup)
• How often you run it (daily use wears pumps and seals faster)
• Cleaning and maintenance (filter, spray arms, drain path)
• Detergent use (too much can cause excess suds and residue)
• Early repair of small issues (minor leaks and slow drains become major failures)

Maintenance that extends life

These steps are the most effective for long-term reliability:

• Clean the filter regularly; replace it if it is damaged (example: dishwasher filter 00615079)
• Keep the drain path clear; address slow draining promptly
• Run hot water at the sink before starting a cycle to improve wash performance
• Inspect the door sealing surfaces and wipe them clean
• Use the correct detergent amount for your water hardness

Common “end-of-life” symptoms (and likely parts)

If you see these issues, the dishwasher can often be repaired, especially if the tub is in good shape.

Symptom	Common cause	Example part on this model page
Not filling or fills slowly	Water inlet valve issue, supply problem	Dishwasher water inlet valve 00622058
Not draining	Drain pump or drain hose restriction	Dishwasher drain pump 00642239
Poor cleaning or weak spray	Circulation pump wear, filter clog	Dishwasher circulation pump 00442548
Leaks at the bottom of the door	Lower door seal wear	Dishwasher door seal, lower 00432490

Why it matters

Knowing the 10 to 15 year life expectancy helps you decide whether to repair or replace. If your Bosch SHE43RL5UC is under about 10 years old, replacing a pump, valve, hose, or seal is often a practical way to restore performance. You can order the parts listed for this model on this page, or search by model number on Sears PartsDirect.

On your Bosch SHE43RL5UC dishwasher, the E24 error indicates a drain problem. You can do a few safe checks first (filter, hose, sink connection); if it still will not drain or you must access wiring or plumbing, we recommend a technician. Use the owner's manual for model-specific self-help.

What to try first (safe DIY checks)

• Cancel the cycle and start a drain; listen for the drain pump running.
• Clean the filter and sump area; a clogged filter commonly triggers drain errors (see dishwasher filter 00615079).
• Check the sink drain or disposer inlet where the dishwasher hose connects; clear any blockage.
• Inspect the drain hose for kinks, crushing, or a fallen high loop; replace a damaged hose with dishwasher drain hose 00668108.
• If you hear humming but no water moves, the pump may be jammed or failing (see dishwasher drain pump 00642239).

When we recommend a technician

Schedule service if any of these apply:

• E24 returns after you clean the filter and confirm the hose and sink connection are clear.
• You see leaking, smell overheating, or the breaker trips.
• You need to pull the dishwasher out to reach electrical connections or water lines.

Quick symptom guide

What you notice	Most likely cause	What to do
Standing water, dirty filter	Restricted drain path	Clean filter and sump
Hose kinked or crushed	Drain hose restriction	Re-route or replace hose
Pump hums, no draining	Pump jam or failure	Clear jam or replace pump

Why it matters

Running with a drain restriction leaves dirty water in the tub, reduces cleaning performance, and increases the chance of leaks at hose connections.
