What 4C means

4C on Dacor Modernist and Contemporary dishwashers such as the DDW24M999US, DDW24M999UM, DDW24T998US and DDW24T999BB tells you to check the water supply. The dishwasher is not getting water the way it should, because the supply valve is closed, the supply to the home is suspended, or the inlet valve or fill line is frozen or clogged. The cycle stops, and you may find the tub empty or only partly filled.

Common causes of 4C

Water supply valve under the sink closed
Home water supply shut off or low
Fill line kinked, frozen or clogged
The dishwasher inlet valve

✓ One safe check you can try

1. Make sure the water supply valve under the sink is fully open. 2. Confirm the kitchen faucet runs normally, in case the home supply is off. 3. Look for a kinked or crushed fill hose behind or beside the dishwasher. 4. If a line may be frozen, warm the room before trying again. If 4C continues, schedule service.

! Why to stop there

Whether water reaches the dishwasher at normal pressure
Whether the inlet valve opens and its screen is clean
Which part is needed, quoted in writing before work

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

4C4C questions

Why does my dishwasher show 4C but my faucet works?

The faucet draws from a different line. The dishwasher's own supply valve may be closed, the fill hose pinched, or the inlet valve clogged. Those are the first things the owner's manual says to check.

Could a clogged inlet valve cause 4C?

Yes. Minerals and sediment can plug the inlet valve or its screen, so water trickles or does not flow. We inspect it during the visit and clean or replace it if needed.

Is 4C urgent?

The dishwasher simply will not fill, so it is not dangerous. If you see water around the unit, close the supply valve and call us or use the online form to schedule service.
