Common problems on the Benchmark#
Here is the Benchmark failure list, most frequent first:
| Rank | Problem | Share of repairs |
|---|---|---|
| 1 | TimeLight LED projector failing or dimming | 15% |
| 2 | E24 drain error | 22% |
| 3 | Home Connect Wi-Fi module losing connection | 12% |
| 4 | Premium stainless tub developing water spots from hard water | 10% |
| 5 | CrystalDry zeolite cassette degradation | 8% |
TimeLight LED projector failing or dimming. It accounts for roughly 15% of Benchmark service calls. It is worth ruling out early, before it drags other components down.
E24 drain error. In the field: identical platform to 800 Series. On the Benchmark it lands at about 22% of repair visits. Catch it early and the repair usually stays contained.
Home Connect Wi-Fi module losing connection. Expect it in near 12% of the repairs logged on this platform. Diagnosing it promptly keeps the fix small.
Premium stainless tub developing water spots from hard water. It accounts for roughly 10% of Benchmark service calls. It is worth ruling out early, before it drags other components down.
CrystalDry zeolite cassette degradation. On the Benchmark it lands at about 8% of repair visits. Catch it early and the repair usually stays contained.
Error codes to know#
The Benchmark surfaces these on the display; each links to a full diagnosis and fix:
- Error E24 — full diagnosis and fix
- Error E15 — full diagnosis and fix
- Error E09 — full diagnosis and fix
- Error E22 — full diagnosis and fix
- Error E01 — full diagnosis and fix
A code that is not listed often clears with a 60-second power cut at the breaker; if it returns, it needs a real diagnosis.

Repair or replace?#
The Benchmark math is simple: under 10 years old and a repair below 50% of a new one, fix it. Over 10 years, if your cumulative repairs across the past two-to-three years top 40% of replacement cost, replacing wins on both cost and a fresh warranty.
| Unit age | Minor fault | Major fault | Critical fault |
|---|---|---|---|
| Under 5 years | Repair | Repair | Repair |
| 5-10 years | Repair | Weigh total history | Consider replacing |
| Over 10 years | Repair if healthy | Consider replacing | Replace |
Maintenance that heads off these failures#
A few habits keep the Benchmark out of the repair queue:
- Clean the TimeLight lens on the bottom of the door with a soft cloth quarterly
- Reset the Home Connect module by cycling the breaker if Wi-Fi drops
- Use the CrystalDry vinegar maintenance cycle monthly
- Install a water softener if hardness exceeds 7 grains per gallon to protect stainless tub

Getting the most life out of your Benchmark#
To keep your dishwasher running efficiently, clean the filter assembly every 1-2 weeks, run an empty hot cycle with dishwasher cleaner or white vinegar monthly, and use rinse aid for better drying results. Load dishes so that nothing blocks the spray arm rotation — the spray arms must spin freely for proper cleaning. Scrape but do not pre-rinse dishes — modern dishwashers need some food residue for the soil sensor to determine the correct cycle intensity.
