If the door of a Haier HLC1700AXW will not open, the manual's answer is the door lock after a dry cycle: the temperature inside has not cooled to a safe level, so wait; the cooling can take several minutes. Haier's support article for washer/dryer combos adds a reset: disconnect power to the unit for 1 minute, restore it and try the door again, and if it still will not unlock the unit needs service. E2 is the unit's own message when it cannot lock the door after 20 seconds.

Model-specific
What is true of this model and not of its siblings
- Cooling before the door opens
- Because the HLC1700AXW dries with a condensing system, the drum can be hot after a dry cycle. Haier's manual says the door will not open after a dry cycle because the temperature inside has not cooled down to a safe temperature, and the remedy is to wait several minutes. This is a safety lock working as intended, not a fault.

Exact questions
Common questions
Why won't the door open after drying?+
The temperature inside has not cooled to a safe level; wait several minutes.
How do I reset a locked door?+
Disconnect power for 1 minute, restore it and try again; if it still will not open, service is needed.
What does Err1 mean on Haier's combination chart?+
The door is not closed; verify the door and latch close completely.
Are flood safe hoses suitable?+
Haier says they restrict the flow of water, so use standard hoses if the fill is slow.
How do I know the door is really closed?+
Close it firmly until you hear it latch, check that no clothing is caught in the gasket, and press Start again, since an unlatched door stops the cycle and can show a door message.
What should I give Haier when I call for service?+
Give the model, the serial number, the code shown on the LED screen and what the unit was doing at the time, so that the agent can find the right step at once.
