Bosch 100 Series Dishwasher — Issues & Fixes

The 100 Series uses the same drain hardware as pricier Bosch tiers but a simpler condensation drying system, so its two headline complaints are draining and drying. Both are well understood. Below are the covered models, the ranked problems with the part behind each, the codes it reports, and a repair-or-replace framework.

Model Specifications#

All four variants share one platform and parts catalog. The line features a 50 dBA rating, a recessed handle or front controls, PureDry condensation drying, a RackMatic height-adjustable upper rack, and AquaStop leak protection.

Common Problems for This Model#

Ranked by field frequency, each with the part behind it:

1. E24 drain error (34%) — the universal Bosch drain fault, using the same pump as higher tiers. The drain pump (BSH 00631200) is cleared or replaced after the filter check.
2. PureDry leaving dishes very wet (22%) — condensation drying is less effective than the zeolite tiers, so maximizing rinse aid matters most here.
3. Door latch not engaging (12%) — the latch arm bends under repeated use. The door latch assembly (BSH 00630783) is the fix.
4. Circulation pump motor humming but not spraying (8%) — an impeller obstruction. The circulation pump with heater (BSH 00442548) is replaced when jammed.
5. Water inlet valve solenoid failure (7%) — no fill after start. The water inlet valve (BSH 00622058) is replaced.

Error Codes#

The panel can display any of these codes:

• E24
• E15
• E01
• E16
• E18

For a code outside this list, cut power at the plug or breaker for 60 seconds and restore it to clear transient faults. A code that returns immediately needs a proper diagnosis.

Before You Call for Service#

A few checks resolve common 100 Series complaints before a visit:

• For E24, clean the triple filter and check the drain hose and disposal connection before suspecting the pump.
• If dishes stay wet, raise the rinse-aid setting, which matters most on PureDry condensation drying.
• If the door will not latch, inspect the latch arm for bending under repeated use.
• If there is no fill after start, confirm the supply valve is open before condemning the inlet valve.

Recall Status#

There are no active recalls on the Bosch 100 Series as of 2026-05-28. Because a recall can be issued at any time, check the Consumer Product Safety Commission at cpsc.gov with your model number and sign up for their email alerts.

Repair or Replace?#

The 100 Series is the entry Bosch dishwasher, so the repair math is simpler. Drain pump and latch jobs are cost-effective and clearly worth doing under 10 years old when the fix is below 50% of a new unit. A circulation pump failure is the borderline case; because it is a bigger job, it is worth comparing against stepping up to a 300 or 500 Series for better drying. After 10 years, once the last two to three years of repairs clear 40% of replacement cost, replacement is the better call.

Maintenance That Prevents These Failures#

• Maximize the rinse-aid setting, which is essential for good PureDry condensation drying at this tier.
• Clean the triple-filter system every two weeks, the same filter used on the 800 Series.
• Run the hottest cycle weekly to dissolve grease in the drain path and head off E24.
• Confirm the drain hose is installed in a high loop to prevent backflow from the disposal.

Expected service life runs 10 to 13 years, and a high rinse-aid setting plus a clean filter prevent the two faults that lead its repair list.
