How to fix Samsung 3E
Check your water heater setting (US and Canada)
Samsung says incoming water must stay below 176°F (80°C), and recommends 120 to 149°F (49 to 65°C) for normal use. Turn the water heater down if it is set very high; that also lowers the risk of scalding at your faucets.
Power cycle the dishwasher
Switch the dishwasher off at its circuit breaker (or unplug it) and wait about 1 minute. Restore power and start a fresh cycle. If the code clears and stays away, it was likely a one-time glitch.
When to call a technician
If the water temperature is normal and 3E keeps appearing, request service.
