Before you book,
in this order.

Each step comes from Samsung's own guidance for 4C on its dishwashers. Follow it to the end: the last card says whether this is a visit.

01

Open the supply valve under the sink fully.

02

Follow the inlet hose behind the machine and straighten any kink.

03

If the supply is fine and 4C persists, book a visit.

Still there?

It usually turns into fill and water valve repair. Book with the code and the model number.

What not to do

Do not assume a 4C means the house has no water. It also covers water that arrives too weakly or at the wrong temperature.

Questions
about 4C.

Can I clear 4C myself?
Open the supply valve under the sink fully. If it comes back, it needs a visit.
Can my Samsung show 4C even though the kitchen tap runs fine?
Yes, the code also covers a supply with too little pressure or water that is not the temperature the machine wants, not only a supply that is off. Turn the under-sink valve fully open and look behind the dishwasher for a bend in the fill hose.
Is 4E on my Samsung the same error as 4C?
It is; certain Samsung models display the water supply error as 4E instead. The owner checks do not change, and a code that persists with good supply needs a visit.

Still showing 4C?

Book with the characters exactly as shown, the full model number, and whether any water is on the floor — for a code, that is where the diagnosis begins.
