Comfee Dishwasher E1 — What It Means & How to Fix It

By Callum Griffin · Researched and verified against manufacturer and repair documentation · Reviewed June 2026

Your Comfee dishwasher didn't fill in time — E1 (the manual calls it 'longer inlet time') is a water-intake fault, usually a tap, hose, or inlet-screen issue.

What this code means

E1 on a Comfee dishwasher is the long-inlet fault: the machine waited for water and not enough arrived before its timer expired. Comfee's own manual lists the likely internal cause as a flow meter, valve, or pump issue, but the things you can check first are all on the supply side.

These are mostly countertop Comfee dishwashers that connect to a faucet adapter, so a loose or half-open adapter is a frequent cause. Built-in and European Comfee models can map their codes differently — check your model's manual if the code pairs with an unexpected symptom.

Most likely causes

CauseHow likelyDIY-fixable?
Tap or faucet adapter not fully open Very common Yes — no tools
Kinked or trapped inlet hose Common Yes — no tools
Clogged inlet screen Common Yes — 10 min
Low water pressure Occasional Partly — check taps
Flow meter or inlet valve fault Less common No — technician job

What you can try yourself

  1. Make sure the tap or countertop faucet adapter is open all the way and sealed.
  2. Straighten the inlet hose and clear any kinks.
  3. Turn off the water, disconnect the hose, and rinse the inlet mesh screen.
  4. Check pressure at a nearby tap to rule out a weak household supply.
  5. Unplug the dishwasher for a minute to reset, then run a short cycle to retest.

When to call a technician

Typical professional repair cost: Inlet valve or flow-meter service on a Comfee dishwasher typically runs $100—$210 including labor.

Frequently asked questions

What does 'longer inlet time' / E1 mean on a Comfee dishwasher?

It means water didn't come in fast enough before the fill timer ran out. Comfee's manual blames the flow meter or valve internally, but check the tap, adapter, hose, and inlet screen first — those are the usual causes.

My countertop Comfee dishwasher shows E1 — what first?

The faucet adapter. Countertop models depend on that quick-connect, and a loose or partly open adapter is the most common reason water doesn't arrive in time.

Could low pressure cause E1?

Yes. If the supply is weak the dishwasher may not fill before the timer expires. Test another tap; poor flow everywhere points to the household supply.
