Steam is escaping from floating valve

normal if from the pressure relief valve

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.

go google and type in -- user manual for mirro pressure cooker model m-0536-1-- and if there is one it will be a pdf version down load
make sure that the lid seal went in without any twists
put something under the seal and go around the lid several time to allow the seal to untwist

When a pressure cooker is working normally, some steam and a little water is supposed to come out of the valve, that's how you know it's up to pressure.

As long as the lid is properly locked into position it should be closed properly. A certain amount of air and steam will escape from the valve on the lid and will male a hissing sound but this is perfectly normal.

Replacement parts for the Wolfgang Puck pressure cookers are difficult to find and I just received an e-mail back from an earlier inquiry to the the company advising that parts are available here:

Yes, otherwise the cooker would blow up from the pressure. This was a common problem with pressure cookers used on a stove from many years ago. Hope this helps!

No. if the steam is coming out, the vent valve is not seated on the vent and pressure won't build up. Either remove the plastic cover from the vent valve or slide it up enough so that the valve seals on the vent. If you remove the plastic cap, you will need to manually tilt the valve to "quick-vent" the cooker. Watch out for steam burns! Should work fine after that. You need to unplug the cooker and re-plug it to reset the "E4" error message.
