Bosch SHY56A05UC/23 dishwasher Parts

Yes, but we recommend you stop using your Bosch SHY56A05UC dishwasher until you clear the E22 condition. On Bosch dishwashers, E22 is commonly tied to a drain or filter restriction; running more cycles can leave dirty water in the tub, reduce cleaning performance, and strain the drain system.

E22 most often points to a drainage problem caused by a restriction in the sump and filter area or the drain path.

Common causes to check first:

• Food debris blocking the filter area (fine filter and sump)
• A kinked, clogged, or improperly routed drain hose
• A drain pump that is jammed or failing
• A drain pump housing obstruction or leak that affects flow
• A float stuck in the up position (can affect fill and drain behavior)

Turn off power at the breaker before inspecting internal components.

1. Clean the filter area

• Remove and rinse the filter components
• Clear debris from the sump area below the filter
• Reinstall the filter securely so it seats flat

2. Check the drain path

• Inspect the drain hose routing for kinks and high loops
• If connected to a garbage disposal, make sure the inlet is clear
• Look for standing water after cancel-drain; that points back to a restriction or pump issue

3. Inspect likely parts if the problem returns

• If you suspect a clogged filter, start with the dishwasher fine filter 00357393
• If the unit hums but will not drain, the dishwasher drain pump 00642239 is a common fix
• If you see leaks or poor flow at the pump connection, check the dishwasher drain pump housing 00267739

E22 is your dishwasher’s way of protecting itself from running with restricted drainage. Clearing the blockage early helps prevent odors, poor wash results, and repeated pump strain.

On Bosch dishwashers like model SHY56A05UC, the most common problems are maintenance-related: a dirty filter or clogged spray arm that causes poor cleaning, odors, or standing water. The good news is these issues are usually fixed with cleaning and a quick inspection, not major repairs.

• Clogged filter or fine filter: gritty dishes, cloudy glasses, food debris left behind
• Spray arm blockage: weak wash action, detergent not dissolving, dirty spots on upper rack
• Drain restriction (hose, pump area, air gap): water left in the bottom, slow draining
• Door sealing issues: drips at the bottom corners or along the lower edge
• Fill or water level problems: poor wash performance because the tub never fills correctly

1. Clean the filter system and remove any labels, glass, bones, or seeds.
2. Spin the spray arms by hand; clear debris from the holes.
3. Check the drain path: sink/disposer connection, air gap (if used), and the drain hose routing.
4. Inspect the door seal area for food buildup and wipe it clean.
5. Run a cleaning cycle using a dishwasher cleaner; then re-check performance.

If cleaning does not restore normal operation, these model-matched parts are frequent fixes:

Most “Bosch dishwasher problems” start as airflow, water flow, or drainage restrictions. Keeping the filter and spray system clean helps the dishwasher heat properly, drain fully, and clean consistently, which also reduces repeat clogs and leak risk.

The model number for your Bosch dishwasher is printed on the appliance’s rating label, not on the control panel. On Bosch dishwashers like SHY56A05UC, the label is typically on the inner edge of the door; open the door and look along the left or right side of the door frame.

Check these common label locations first:

• Inner door edge (left or right side) when the door is open
• Door frame around the tub opening
• Top edge of the door (visible only when the door is open)
• Side of the tub opening near the front

Bosch labels often show multiple identifiers. For ordering parts, we recommend recording:

• Model number (use the full model, for example SHY56A05UC)
• FD number (factory date code, if listed)
• Serial number
• Type or E-Nr (common on Bosch labels)

Bosch dishwashers can have small design changes within the same series. Using the full model number from the rating label helps ensure parts like a dishwasher door latch 00187185 or dishwasher drain pump 00642239 fit correctly.
