My Wolfgang Puck pressure cooker shows 'E4' in the display.

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 had this problem. I noticed that steam was coming out almost immediately and the cooker would not start counting down. 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. The plastic cover was so far down on the metal piece that it would not allow the metal cylinder to seat on the vent. You can use the metal piece by itself or work the plastic cap up far enough so that the metal piece seats on the vent in the closed position. I have had no more problems - it works fine.

Jumping it works great ty
