Quick answer: Haier dishwasher error codes E1–E4 follow a logical sequence — inlet (E1), drain (E2), temperature sensor (E3), anti-flood base (E4); in most Australian homes E2 is the most common, usually resolved by cleaning the filter, and E1 often just means the tap has been bumped off.

Haier dishwasher error codes explained
Haier dishwashers — including the HDW9TFE3SS, HDW9TFE3WH, HDW12-TFE3SS, HDW12-SFE3SS, HDW12-SFE3WH, HDW15G3X, HDW13G1X, HDW14G2X, DW60CCW1, DW60CCX1, DW60CEW1, and DW60CEX1 — display fault codes as E followed by a number on the control panel. The machine stops mid-cycle and holds the code until you clear the fault.
Codes E1 through E4 cover the four main systems: water inlet, drainage, temperature sensing, and anti-flood base protection. A fifth code — E6 — can appear on some models as a turbidity (water clarity) sensor fault; this is less common and discussed briefly below. The core codes are the same across the HDW9, HDW12, and DW60 series, though some older variants may present them slightly differently — always verify against your model sticker on the door frame.
Haier dishwasher error codes — cause and likelihood table
| Code | Meaning | Cause | Likelihood |
|---|---|---|---|
| E1 | Water inlet fault — fill timeout exceeded | Tap under sink turned off or only partially open | Very common |
| E1 | Water inlet fault | Kinked or crushed inlet hose behind the machine | Common |
| E1 | Water inlet fault | Inlet valve solenoid failed — no flow despite tap being open | Common |
| E1 | Water inlet fault | Low water pressure to property (peak demand or supply issue) | Occasional |
| E2 | Drainage fault — water not pumping out within time limit | Filter blocked with food scraps or accumulated grease | Very common |
| E2 | Drainage fault | Drain hose kinked or sitting too low (no high loop) | Common |
| E2 | Drainage fault | Sink waste connection blocked or garbage disposal knock-out plug in place | Occasional |
| E2 | Drainage fault | Drain pump motor failed or impeller jammed | Moderate |
| E3 | NTC temperature sensor fault — heating circuit issue | NTC sensor open-circuit or short-circuit | Moderate |
| E3 | Temperature fault | Heating element failure — water not reaching target temperature | Moderate |
| E4 | Anti-flood / overflow — water detected in base pan | Door seal weeping or inlet hose connection dripping | Occasional |
| E4 | Anti-flood / overflow | Pump housing or sump crack letting water into base | Less common |
| E4 | Anti-flood / overflow | Excessive suds (wrong detergent) causing overflow into base | Occasional |
E6 — turbidity sensor fault: Some Haier dishwasher models include a turbidity (water clarity) sensor that monitors how dirty the wash water is. If this sensor fails or becomes coated in mineral deposits, E6 may appear. This fault is less common than E1–E4. Try descaling the sensor before replacing it. If you see E6, use the part finder quiz to identify the correct sensor for your model.
How to fix Haier dishwasher E1 — water inlet fault (step-by-step)
E1 is one of the most easily resolved Haier dishwasher faults. Before ordering any parts, work through these checks in order.
- Check the tap under the sink. The isolation tap that feeds the dishwasher should be turned fully anti-clockwise (open). It is surprisingly common for this tap to be knocked closed during cleaning or when storing items under the sink. Open it fully and run a short rinse cycle.
- Inspect the inlet hose. Pull the machine forward slightly (or open the kick panel) and trace the inlet hose from the tap to the back of the machine. The hose should have a smooth curve with no sharp bends or kinks. If the hose is pressed hard against a cabinet wall or has been twisted, straighten it and retry.
- Test water pressure. Turn on the kitchen sink tap at full flow. If the pressure feels very low — a thin, slow stream — the supply pressure may be insufficient for the dishwasher to fill in time. Haier dishwashers typically require a minimum of 0.04 MPa (approximately 5.8 psi). Low pressure at this level needs to be addressed at the plumbing level.
- Listen for the inlet valve during fill. Start a cycle and listen at the side of the machine during the first 30 seconds. You should hear a faint click as the inlet valve solenoid opens, followed by a quiet rushing sound as water enters. If you hear the click but no water, or no click at all, the inlet valve is not opening and likely needs replacement.
- Replace the inlet valve. If all the above checks are clear, the inlet valve solenoid has failed. Turn off the water at the tap, disconnect the power, and remove the kick panel to access the valve. Disconnect the inlet hose (have a towel ready) and the electrical connector, then fit the replacement valve.

How to reset a Haier dishwasher after fixing a fault
After resolving the underlying cause, reset the machine by pressing Cancel or switching off at the power point. Wait thirty seconds before switching it back on. Select a short cycle such as Quick Wash and run it through to completion to confirm the error code does not return.
For E4 (water in base), you must remove the water from the base pan before the anti-flood float switch will reset. Tilt the machine forward slowly (with someone to help) until you hear the water running back through the sump, or remove the kick panel and sponge the water out manually. Do not run another cycle until the leak source has been found and fixed.
Frequently asked questions
My Haier dishwasher shows E1 but the tap is open — what else could cause it?
With the tap confirmed open, the next most common cause is a kinked inlet hose — check behind and underneath the machine. If the hose is clear, the inlet valve solenoid is the most likely culprit. It is a relatively inexpensive part and straightforward to replace. Use the model number from the sticker on your door frame to confirm the correct replacement.
How often should I clean the filter on my Haier dishwasher to avoid E2?
For a household running one or two cycles per day, clean the filter every two to four weeks. If you regularly wash heavily soiled items or do not pre-rinse dishes, clean it weekly. A blocked filter is the single most common cause of dishwasher faults — regular cleaning prevents E2 and also keeps wash results sharp.
Where is the model sticker on a Haier dishwasher?
Open the dishwasher door and look along the left-hand edge of the door frame. The model sticker lists the full model number (e.g., HDW12-TFE3SS) and serial number. Keep a photo of it on your phone — it is needed every time you order a spare part.
My Haier dishwasher shows E3 but dishes are coming out warm — is it the element or the sensor?
If dishes are warm but not fully dried and the cycle is running longer than normal, the NTC temperature sensor is the more likely fault — it is reporting a lower temperature than actual, causing the machine to extend the heating phase. If dishes come out cold and wet with no heat at all, the heating element itself has more likely failed.
Can I use any dishwasher tablet in my Haier to avoid E4 from suds?
Use tablets or powder specifically labelled for automatic dishwashers. Standard hand dishwashing liquid produces far too many suds and will cause the machine to overflow into the base pan, triggering E4. If you have accidentally used hand wash liquid, run two or three empty rinse cycles to clear the suds before attempting a normal wash.
