Dishwasher Error Codes: What Your Display Is Telling You

A blinking light or a two-letter code on a dishwasher display is a real diagnostic signal, not a mystery. Find your brand and code below for what it means, what usually causes it, what you can safely check yourself, and when it's time to call a technician.

Look up by brand

Start here if you already know which dishwasher you have.

• BoschE-series fault codes
• SamsungLE, OE, 5E/SE and more
• LGOE, IE, LE, AE and more
• WhirlpoolF-series fault codes
• KitchenAidF-series and H2O codes

Don't know the code yet? Search it

The code lookup tool searches every documented code by the letters/numbers on your display, by brand, or by a keyword from what it means — faster than scrolling a brand page if you already have the code in hand.

No code showing — just a problem?

Plenty of dishwasher problems show up as behavior, not a code on the display. These symptom pages start from what the dishwasher is doing:

• Dishwasher Not Draining
• Dishwasher Not Filling With Water
• Dishwasher Leak Detected / Water Under the Unit
• Dishwasher Door Won't Latch or Close
• Dishwasher Not Heating, Drying, or Sanitizing
• Dishwasher Blinking Lights With No Error Code Shown
• Dishwasher Won't Start
• Dishwasher Stuck or Stopped Mid-Cycle

What repairs typically cost

Repair-cost aggregators generally agree on ranges, though your actual bill depends on region, brand, and whether it's a part or a board. Angi (angi.com, 2026 data) puts the average dishwasher repair around $100–$300, with a wider real-world range of about $70–$600 depending on the problem. HomeGuide and Forbes Home cite similar bands: roughly $150–$400 for common fixes like a clogged drain pump, door latch, or water inlet valve, and $200–$600 installed for a control board replacement (more if it's an OEM part versus a generic one).

Forbes Home and HomeGuide both note a standalone drain pump replacement runs about $100–$400 in parts and labor, while door latch repairs are on the cheaper end at roughly $100–$250 total even though the latch part itself is often only $10–$50. Expect a diagnostic/service call fee of about $70–$130 from most independent repair companies, which many outfits (per Angi and HomeGuide) will credit toward the repair if you go ahead with it. Built-in premium brands like Bosch and KitchenAid tend to run toward the higher end of these ranges for parts availability and labor time versus more budget-oriented brands.

These are general ranges from industry cost guides, not quotes for your specific job — always get a written estimate from a local technician before authorizing repair work. For a fuller breakdown by part and by fault-code family, plus repair-or-replace guidance, see the full repair cost guide.

How this site works

Every code page names the specific models a code applies to, explains what the fault actually means mechanically, lists the common real-world causes in order of likelihood, gives the checks a homeowner can safely do, and says plainly when the job needs a licensed technician instead. No fault code is published here unless its meaning can be verified against a manufacturer manual, manufacturer support page, or a documented repair reference — see About & methodology.
