# Samsung dishwasher pump replacement

### Two pumps, and they are not the same part

The wash pump circulates water round the tub and Samsung reports its failure as 3C. The drain pump empties the machine. They fail differently, they sound different at the start of a cycle, and they cost differently — so which one it is gets established before anything is ordered rather than after. Seals and the sump gasket go back with either.

What this involves

Wash pump and drain pump diagnosed separately

3C confirmed rather than assumed from a silent machine

Seals and the sump gasket replaced with the pump

Listen at the start of the cycle

Silence where there should be circulation, a labored hum, or a grinding noise each point somewhere different.

Prove which pump before ordering

The wash pump circulates and the drain pump empties. They sound different at the start of a cycle and they are different parts.

Replace the seals with it

A pump refitted with its old sump gasket is a leak repair booked for later.

Run a full cycle afterwards

With the machine watched at fill, wash and drain, because a pump is easy to fit and easy to fit slightly wrong.

### Can I hear the difference myself?

Often, yes. Silence where there should be a circulating hum at the start of the wash points at the wash pump. A machine that washes normally and then sits full points at the drain pump.

### Will you tell me the price before you start?

Yes, in writing, after the diagnostic and before anything is opened. Every figure on this site is a starting point; the number you agree to is the one you pay.
