The short answer
The order that matters here is the door lock not confirming first, the drain and the level sensing next and the control board and its wiring last. On a current mass-market machine the electronics are good enough that the ranking leans towards the things the owner touches — the load, the door, the filter and the supply. That ranking is the value of this page: the cheap causes are the common ones on Haier washer-dryer combinations, and the costly one is what people reach for first.
What you observe
- The door stays locked with the panel lit — Water in the drum, or a lock that is not releasing, holds the door by design.
- It faults only on cycles that include drying — That separates the condensing side from the washing side straight away.
- It stops at a different point every time — No pattern points at the supply or at the lock rather than at a specific system.
- NEAR MISS — it will not start at all — A dead machine is a start fault, and the will-not-start page for this appliance class is the right read.
Causes, most likely first on Haier
- The door lock not confirming — A combination machine checks its lock continuously, through a wash and through a hot dry phase. A lock that is marginal will confirm at the start and drop out once the machine heats or moves, and the control reports that as a fault. Ranked first on Haier: it is first because both halves of the machine depend on it and it is the part that gets hottest on every dry cycle.
- The drain and the level sensing — A combination machine has to empty the drum completely before it can heat it. Placed there because it is second because the transition to drying is where these machines fault, and the drain is what gates that transition.
- Temperature sensing on either half — This shows as a cycle that either never ends or ends far too soon, with no mechanical symptom at all. Third, once the two above are clean: it is here because the symptom is a cycle that never ends or ends far too soon, with nothing mechanical to see.
- The control board and its wiring — Because everything in this appliance reports as a control fault, the board gets blamed for faults that belong to the lock, the drain or the supply. Bottom of the list, deliberately: it is last because every fault on this machine reports as a control fault, which is exactly why the control is rarely the cause.
Check in this order, and why
- First: Press the door firmly and restart — A cycle that proceeds while the door is held names the lock and nothing else. It is first because it is the cheapest of the three to settle.
- Second: Open the pump filter and check the hose — Have a tray ready. Then look behind the machine for a kink in the drain hose.
- Third: Does it run forever or stop early? — Either extreme, with a clear drain and a normal load, points at temperature sensing.
What an owner can safely check
- Close the door firmly and run a short cycle — Start a short wash with a hand holding the door shut and see whether it proceeds.
About 10 min
- Clear the pump filter and straighten the hose — Empty the filter chamber into a shallow tray, then check the drain hose for kinks and its height.
Tools: shallow tray, towelAbout 25 min
- STOP HERE if the next step needs a meter on live terminals — That is the line between an owner check and a service call, and it is not worth crossing.
Before any panel comes off
Safety
Unplug the appliance or switch off its breaker before removing any panel, and treat every capacitor as still charged: a capacitor can hold a charge after the power is off. Drain the tub through the pump filter into a shallow tray before moving the machine, and expect the water to be hot if the cycle stopped part-way through a wash.
When to call a technician
Call once the lock is confirmed, the pump filter is clean, the drain hose is straight, a half load on an unshared outlet still faults, and the cold supply to the condensing circuit is open — what remains is sensing and control, and both are meter work. Call sooner if the machine trips its breaker, or if the drum is very hot at the moment it faults, because an over-temperature stop is a protection working rather than a nuisance.

What this page does not cover
This is generalized information for Haier washer-dryer combinations as a class, not for one family or one model. No family- or model-specific page for this brand and appliance is published here yet, so nothing narrower is linked; when one is, it becomes the more specific answer and this page will point to it. Deliberately absent: part numbers, wiring colours and the order the panels come off in — those belong with a named family.
