About Dishwasher Error Codes

What this site is, where the information comes from, and what it deliberately does not do.

What this site is

Dishwasher error codes are real, documented, and genuinely useful once you know what they mean — but that information is scattered across PDF service manuals, brand support pages with inconsistent naming, and forum threads of wildly varying accuracy. This site collects the codes for five major dishwasher brands — Bosch, Samsung, LG, Whirlpool, and KitchenAid — into one page per code: what it means, what commonly causes it, what a homeowner can safely check, and where the line is between a DIY fix and a technician call.

Independent, not affiliated

This site is not affiliated with, endorsed by, or connected to Bosch, Samsung, LG, Whirlpool, KitchenAid, or any other manufacturer named on it. Brand and model names are used only to identify which manufacturer's equipment a given code applies to — the same way a repair manual or a parts catalog would reference them.

How pages are written and checked

Pages are drafted with AI assistance and checked against manufacturer service documentation, manufacturer support pages, or established documented repair references before publishing. A code's meaning is a fact and is reported as a fact; no manufacturer manual text is copied wholesale. Code behavior varies by brand and sometimes by model generation within a brand, so every page states which models it applies to. A code is not published here unless its meaning could be verified against a real source — if a code can't be confirmed, it's left out rather than guessed at.

What this site does not do

No fabricated customer testimonials, reviews, or "as seen on" claims
No invented author bios or credentials
No invented statistics — any number on this site (a code count, a cost range) is real and traceable to a stated source
No fake-precise repair costs — costs are given as ranges from named industry cost guides, never a single suspiciously exact dollar figure
No pretending to be, or to speak for, any dishwasher manufacturer

Repair costs

Where a page mentions what a repair typically costs, the figures come from published industry cost guides (Angi, HomeGuide, Forbes Home) rather than being invented, and are always shown as a range rather than a single number, because actual cost depends on region, the specific part, and labor rates. See the cost overview on the homepage for the current ranges and their sources. These are general guidance, not a quote — get a written estimate from a local technician before authorizing any repair.

Coverage

The site currently documents codes across five manufacturer groups — Bosch, Samsung, LG, Whirlpool, and KitchenAid — plus a set of symptom pages for cases where a dishwasher is misbehaving without displaying a specific code. Coverage grows one verified code at a time; a brand or a code being absent means it hasn't been verified yet, not that it doesn't exist.

Corrections

If something here is wrong, the fastest way to check is the sources listed at the bottom of each code page — every page names the document or reference it was built from so the reasoning can be checked rather than taken on trust.

This site is an independent reference, not a substitute for a licensed appliance technician or electrician, and is not affiliated with Bosch, Samsung, LG, Whirlpool, KitchenAid, or any other manufacturer named here. Dishwashers combine mains-voltage electrical parts with water. Always shut off both power and the water supply before opening the tub, pump, or heating element housing, and if a repair goes beyond checking filters, hoses, detergent, and visible debris, call a licensed technician.
