At Haier, Err1 and E1 can point to different systems. Keep all letters: the documentation for Haier USA combo washer-dryers does not allow the Err prefix to be dropped.
Check that the table matches a combo unit
The Haier Appliances source used here covers equipment that washes and dries. A front-load machine without drying, or a top-load model from another market, needs its own manual even if it shares the brand.
The prefix changes the search
| Wording | Search |
|---|---|
| Err1 / E1 | Door close / drain time. |
| Err2 / E2 | Drain fault / door lock. |
| Err5 / E4 | Both point to filling within their respective series; no universal equivalence is claimed. |
The display photo prevents a shortened search from leading you to the wrong filter when the appliance is indicating closure. Also note whether the fault appears while filling, draining, or switching to dry.
How far a home check should go
Visible hoses, the load, and the door can provide useful observations. Filter cleaning should only be done where the manual allows it and after preparing for a safe drain. FA and other circuit messages require service; their meanings are not filled in from refrigerator or air conditioner tables.
E13 lint in a combo unit and Unb while spinning have different paths. A cleaning procedure from one family does not automatically carry over to another.
Frequently Asked Questions
Do E1 and Err1 mean the same thing in Haier?
Not in the Haier USA combo table consulted here: Err1 corresponds to door close and E1 to draining. Dropping letters changes the search.
Why do E2 and Err2 point to different systems?
Because they are messages from different series. In this documentation, Err2 indicates a drain fault and E2 a door lock fault. They must be searched in full.
Which alerts apply only to washer-dryers?
E13 is covered here within combo washer-dryers. Drying-related alerts can only apply to a washer that includes that function and documents them in its manual.
How do I confirm that a table applies to my model?
Compare the model number on the nameplate with the manual cover and the appliance type. The generic title "Haier codes" does not prove that it includes your platform.
First select the full wording and confirm the appliance; similar numbers do not prove the same fault.
