# Samsung ice fill tube and heater service

### A small heater with one job

There is a heater wrapped around the tube that fills the ice maker, and all it does is stop that tube freezing shut between fills. Samsung publishes a code for it, 33E. When it stops working the tube ices over and the machine quietly stops making ice — which looks exactly like a failed ice maker and is a considerably smaller repair.

What this involves

33E diagnosed as a heater rather than answered with a new ice maker

Fill tube cleared and the supply pressure checked at the same time

The far cheaper half of most no-ice calls

Clear the tube and watch a fill

A tube that clears and then re-freezes within a day is the heater. One that stays clear and still will not fill is the valve or the supply.

Warm air rather than hot water, and then a full fill cycle observed. A tube that clears and re-freezes within a day is the heater.

Measure the heater and its circuit

It is a small part and it is tested rather than assumed, because the same symptom comes from a valve that is not opening.

Check the supply pressure at the same time

A slow fill and a frozen tube produce the same complaint, and telling them apart takes one measurement.

### How do I know it is the tube and not the ice maker?

A visible plug of ice at the tube is the tell. So is an ice maker that works again for a day after being cleared and then stops, which is the tube re-freezing.

### 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.
