E4 code on model epc460 pressure cooker

I think it has to do with the little valve on the lid sometimes mine gets stuck closed so I move it around a bit and it seems to fix it.

Back in the day when I used a pressure cooker the valves were universal, it was the gasket you had to get right.

It seems over heating problem and most likely sensor is defective ,check out with manfactures support line for replacement or service .do not try to fix it your self ,it is very dangerous !!!!

okay thank you

Generally, the E4 error code means that the sensor in the pc is faulty and needs to be replaced. Contact the place where you bought it immediately (if it's still under warranty) or contact the manufacturer to ask for a replacement.

Good Luck!

Well, it depends on the model, I looked the digital pressure cooker manual (found here http://www.hippressurecooking.com/category/manuals/cooks-essentials/) E4 is a Signal Switch Malfunction. The recommend turning off and un-plugging the pressure cooker and letting it cool of completely before trying to use it again.

Make sure the inner container is dry... plug he unit off then on again.

Eventually, the "E4" display would appear. I determined the steam vent valve (loose piece) was not seated on the vent hole in the cover so the pressure never built up. I removed the loose piece which consists of a metal cylinder and a black plastic cover with a handle.

Did you ever figure out how to replace the float valve on your pressure cooker?

There doesn't seem to be any legit way of fixing this. I tinkered with the pressure sensors and valves, kicked the pressure cooker a few times, still the E4 error presented itself.


I was able to bypass the E4 error by completely bypassing the electronics and wiring the heater coil to get power whenever the pressure cooker is plugged in. It was a very simple job, anyone with any electrical experience can do this.

The only problem is that it is a safety concern as there is no way for the heater to turn off even if pressure is getting to be way too high. There may be a pressure relief valve in the lid but the heater coil won't shut off, so don't leave it unattended! But at least this way to you can still pressure cook.

I fixed mine by elevating it 4 inches (E4) and dropping it on the counter. Something needed a little impact adjustment!
