How we check error codes
A wrong answer in an appliance reference costs someone a call-out fee, a part they did not need, or a machine they threw away too early. That is why the method matters more than the size of the catalogue.
The rule every page follows
A code gets a page only when its meaning is confirmed by the manufacturer's own documentation and at least one independent source, usually a repair trade that works on these machines daily. If the two disagree, no page is published until the disagreement is resolved.
This is slower than the alternative, and the alternative is everywhere: take a list of codes from one page, reword it, publish a hundred pages in an afternoon. Those lists carry each other's mistakes for years.
Two codes are missing from this site for exactly that reason. Bosch reads E:10 on a washing machine as a blocked dosing pump; independent repairers read it as a drain problem. Those are different parts and different money, so there is no page until we can say which is right.
What is on a code page
Every code page answers the same seven things in the same order, because that is the order the questions actually arrive in:
- what the code means, in one sentence, with no preamble
- whether the appliance is safe to keep using
- what to check yourself, cheapest and most likely first
- where the line is that you should not cross
- what the repair costs, as a range, with the part priced separately
- which codes get confused with this one
- which machines it applies to, and when we last checked it
Points three and five are the ones missing almost everywhere else. Most answers stop at the translation, which is the part you could have guessed.
Where the prices come from
Repair costs are typical United States ranges for 2026, collected from several independent cost surveys and cross-checked against each other. They are ranges rather than single numbers because the real spread by region, model and how buried the part sits is genuinely wide, and a single number would be a false promise.
Where a repair is free, we say it is free. A good share of the codes here are cleared with a filter rinse or a change of detergent dose, and a reference that sends everyone to a technician is not being careful, it is being useless.
Codes, facts and copyright
That a given code means a drain fault is a fact, and facts are not owned by anyone. The wording a manufacturer uses to describe it is theirs. So we take the fact and write our own text, every time. Nothing here is a manual pasted in and shuffled around.
Manufacturer sources are linked at the bottom of each page so you can check us. We are not affiliated with any appliance manufacturer, and brand names are used only to identify the machines the codes belong to.
What is here so far
25 codes across 3 appliance ranges, plus 4 guides for faults that never show a code at all. That is deliberately small. The catalogue grows brand by brand, in the order real search demand justifies, rather than all at once.
Found something wrong, or a code that behaves differently on your model? That is worth more to this site than any amount of new pages. Write to info@signalsxp.com.
