The lid on our power pressure cooker is stuck on, the inside pan is not in the cooker, hiw do we get it open?

Hi,
There are two parts to the 'float valve' pin which has fallen out.
The pin itself pushes back in from the underside of the pan lid,
BUT,
there should be a clear silicone grommet or washer, which slides over the pin from the outside. This is what holds the 'float valve' pin in place & stops it falling into the pan in use.
If you've lost the original grommet in the washing-up, there might be a spare which came in the original box with the pan.
If not, you can order the replacements from the manufacturer or on eBay.

Best of luck.

Try two things one is the opposite of the other.
First try reheating the cooker , as it cools tap the side that might release the lock.

Or cool the lid down alot with ice cubes and see if that works. Just be careful of the electronics

You don't give us the model number of the cooker. Here's a link to a new RH cooker, might be yours. http://www.russellhobbs.co.za/media/32069/rhep7_instruction_manualhttp://www.russellhobbs.co.za/media/32069/rhep7_instruction_manual_rh_electric_pressure_cooker_6l_amended_as___25.02.16.pdf

To open the lid correctly: Hold the handle of lid, turn it anticlockwise until the "DOWN ARROW" mark on the edge of the lid matches up with the "UP ARROW" mark on the edge of the housing cover. Now lift the lid to open. Note: For new pressure cookers, the seal of the lid may be slightly stronger than normal and may be slightly difficult to unlock. Once the lid has been opened and closed several times, it will loosen up.

What has likely happened is when the cooker heated up, the air expanded and escaped, when it cooled off, an air tight seal developed and the top acted as a valve and now the pressure is lower inside the cooker than outside. You need to break the vacuum... This may be done by gently prying the top a bit (carefully so as not to break it) or reheat the cooker. Is there liquid still inside? You could either turn it back on or possibly heat the entire cooker.

it could have built up pressure during storage and shipping, try running hot water over the lid which should cause the lid to exspand and release, hope this helps

Go to this site http://www.crock-pot.com/CustomerService.aspx?id=rpt and put in your model number (located on the bottom of the unit) and you can order the liner and other parts for your crock pot.

Halt, do not use this pressure cook. The lid is suspose to lock. This means the lid become a dangerous fly object if it came off under pressure, plus extremely hot boiling water and the contents of the pressure cooker. Beside possible dying from the lid, and if one survives the flying lid, one will be will scalded by the contents of the pressure cooker. Another pressure cooker manufactured in China.

Russel Hobbs makes both a slow cooker and a pressure cooker - confusingly in Europe they call Slow Cookers pressure cookers. The only way to really tel is if there is a special lid with valves and locks (pressure cooker) not a glass or plain lid (slow cooker).

I think E2 means open circuit in thermocouple in center of bottom. E4 means no contact on pressure sensing switch at edge of bottom. Mine had E4 error. Took out switch and used fine sandpaper to clean contact points. Now it works fine.
Remove 3 screws in bottom. Remove bottom cover by turning it ~1/4" to clear tabs. Remove switch at edge of bottom with two blue wires going to it. Clean contacts and replace.
