What Hot & Small / Hot & Low means
On Samsung washers without a digital display, the Hot light blinking with the Small or Low light is the pattern for a hot and cold error, which is listed as the hoses being swapped. The control senses that the hot and cold inlet connections are reversed, so the water that arrives does not match the setting. The washer can stop before or during fill.
Common causes of Hot & Small / Hot & Low
- Hot hose connected to the cold valve
- Cold hose connected to the hot valve
- Inlet hose labeling at the washer
1. Turn off both water supply valves. 2. Check that the hose marked hot goes to the hot valve and the hose marked cold goes to the cold valve. 3. Switch them if reversed and tighten by hand. 4. Open the valves and restart; if the lights blink again, request service.
- If the hoses are correct and the lights stay, the temperature reading is the next check.
- We test the sensor and the inlet valve response.
- We confirm the connections do not leak.

Does swapping hoses really cause this?
Yes. The washer expects hot water at the hot inlet and cold at the cold inlet. If they are reversed, the control flags it. Telling us which hose goes where helps us confirm it.
How do I tell which is which?
The hoses are usually marked hot and cold, and the valves at the wall match. Check both ends. If the hoses are not marked, the wall valves usually have a red or blue handle or label. Check both ends before tightening.
Is a leak possible after swapping?
Tighten by hand and check for drips with the valves open. If one drips, tell us. If one leaks or the connection feels loose, tell us before running another load.
