Error E1 on Hisense dishwashers

What E1 may indicate on a Hisense dishwasher

On Hisense dishwashers, the E1 error can vary depending on the model. In official manuals it mainly appears in these two ways:

• Door open during operation: the unit detects the door isn’t fully closed/latched and it stops the cycle
• Water inlet problem: the machine tries to fill, but the inlet is restricted or the water pressure is too low

The quickest way to narrow it down is to note when it shows up:

• If E1 appears right after opening the door or when it isn’t properly closed, it’s usually a door issue
• If E1 appears at the start, when it should fill and it doesn’t progress, it’s usually water inlet

How to clear E1 and what to check so it doesn’t return

To fix E1 logically, first identify whether you’re dealing with a door warning or a filling issue. That way you avoid repeating pointless tests.

1. If your E1 is “door open”: make sure it latches perfectly
   • Open and close it again, checking that nothing is blocking it (racks, dishes, gasket)
   • Close until it locks firmly
   • On many models, once the door is closed the cycle resumes after a few seconds
2. If your E1 is “water inlet”: check supply and restrictions
   • Make sure the shut-off valve is fully open
   • Check the inlet hose isn’t bent or crushed behind the cabinet
   • If your connection has a mesh/filter, clean it (limescale and debris reduce flow)
   • If your home has low pressure or a water outage, wait until it returns to normal
3. Do a full reset to clear the fault state
   • Turn the dishwasher off
   • Disconnect it from power for 5 minutes
   • Plug it back in and run a short program, watching the start-up
4. Check whether the fault is constant or intermittent
   • Constant at start-up: consistent with a real fill problem or a door that won’t latch
   • Intermittent: often points to a loose latch, dirt on the gasket, or a contact that fails from time to time
5. What NOT to do
   • Don’t force the door if it won’t close: first find what’s preventing it from closing
   • Don’t keep restarting in a loop if the unit tries to fill and returns to E1
6. When it’s best to call service / a technician
   • E1 returns even though the door closes perfectly and nothing is in the way
   • E1 remains despite having water, proper pressure, and a clean inlet filter
   • The unit never fills or repeatedly stops “halfway”

   At that point, they usually check the latch/lock assembly (if it’s the door) or the inlet valve / related sensors (if it’s filling), as well as connections and wiring.

E1 is quick to resolve when you identify the right cause: if it’s the door, you correct the closure; if it’s water inlet, you remove the restriction and reset. If the code persists with everything OK, a technical diagnosis becomes the most efficient way to go straight to the component responsible.
