If the Haier HLC1700AXW does not take in water, Haier's manual gives four causes: the inlet hose is not connected to the tap, the water tap has not been opened, the tap or valve may need to open more fully (and hoses must not be kinked, twisted or tangled), or there is no water supply in the house or the pressure is too low. Haier's combination chart adds Err5, the unit not sensing a full water fill, with a note that flood-safe inlet hoses must not be used because they restrict flow. E4 is the manual's code for a selected water level not reached after 8 minutes.
Differential
Likely causes of “Haier HLC1700 washer/dryer combo will not fill with water or fills too slowly”, and how to tell them apart
- 1
Taps closed or hoses not connected
What separates it No water enters and the unit waits because the taps are closed or the hoses are not connected
How to confirm Open the taps fully and check the hose connections
- 2
Kinked, twisted or tangled hoses
What separates it The fill is slow because the hoses are kinked, twisted or tangled
How to confirm Make sure that the hoses are straight, and free of twists and tangles
- 3
Flood-safe inlet hoses
What separates it Err5 or a slow fill shows because flood safe inlet hoses are fitted
How to confirm Replace the flood safe hoses with standard hoses, and try again
- 4
Low household water pressure
What separates it E4 shows after eight minutes because the household water pressure is low
How to confirm Check another faucet in the house for adequate pressure
Before you touch a setting
Record this first — changing settings destroys the evidence
- The code that the display shows
- Whether flood safe hoses are fitted to the unit
- The pressure at the other faucets in the home
Try in this order
0 of 5 completedOpen the taps
ReversibleOpen the taps, by opening both fully, and check that the hoses are connected to the taps.
Straighten the hoses
ReversibleStraighten the hoses, so that they are not kinked, twisted or tangled, and then test again to see whether it helped.
Remove flood-safe hoses
ReversibleRemove flood safe hoses, since Haier says that they restrict the water flow, and then test again to see whether it helped.
Check pressure
ReversibleCheck the pressure, by trying another faucet in the house, and then test again to see whether it helped.
Clear the code
ReversibleE4 means the level was not reached in 8 minutes; fix the supply and restart.
Model-specific
What is true of this model and not of its siblings
- Water connection in the manual
- Haier's installation section (page references in the troubleshooting table) covers connecting the inlet hoses. In the troubleshooting table the first check for no water intake is that the inlet hose is connected to the tap and the tap is open, and the last is that there is water supply in the house and adequate pressure, checked at another faucet.
- Cold water for the dryer
- Haier's troubleshooting table says the dryer will not dry properly if the water supply is not properly connected, typically when a Y-adapter is used, and asks you to make sure only cold water is turned on for the condenser. So a fill fault is worth fixing even if washing seems fine, because the condensing dryer depends on the cold supply to remove moisture from the load.

Exact questions
Common questions
Why is my Haier HLC1700AXW not filling?+
Taps closed, hoses not connected or kinked, flood-safe hoses, or low water pressure.
What is the water pressure range?+
4.4 to 145 psi (30 to 1000 kPa) per the manual.
Can I use a Y-adapter?+
Haier notes an improperly connected supply, typically a Y-adapter, can affect drying; connect properly.
Which water does the dryer use?+
The dryer uses cold water for condensing, so keep the cold tap on.
