What F4E4 Means
Whirlpool describes F4E4 as Low or No Line Voltage: there may be a problem with the home power supply that is stopping the dryer's heater working. Electric dryers need a 30-amp circuit fused on both legs, which means two breakers - the drum can turn on one leg while the heater sits dead on the other, which is exactly what this code catches.
Common Causes of F4E4
- One leg of the 240V supply lost at the breaker
- Tripped or failing double-pole breaker
- Loose connection at the outlet or terminal block
- Supply voltage genuinely low at the property
🔧 One Safe Check You Can Try
Touch any pad to clear the code from the display. Then go to the consumer unit and look at the dryer's breaker: on a double breaker, reset both halves firmly off and then on. A tumbling drum with no heat is the classic sign of one leg lost. If resetting the breaker restores heat, keep an eye on it - a breaker that trips repeatedly is warning you about something, not misbehaving. If the breaker is fine and the dryer still runs cold, the supply or the dryer's heating circuit needs testing by a qualified person.
⚠ Why You Shouldn't Go Further Than That
- Testing a 240V circuit means live working - that is an electrician's job.
- Terminal block and heater circuit work inside the dryer belongs to a technician.
