The cream whippers have a safety valve built into the head - it is located just below the thread that the charger holder screws on to. If you experience gas coming out of this valve it means that there is a problem with your whipper that you may be able to solve yourself. Here is a list of likely causes:
Too much pressure in the whipper. This may be because you are filling it with too much cream or because you have charged it with more than the recommended number of chargers. Please use 1 for 1/2L.
The outlet valve (which is attached to the trigger release) may be blocked - please dismantle the whipper head and clean the gas outlet valve with the bristle brush that came with the whipper.
The inlet valve (which pierces the cartridge) is frozen causing it to be blocked. If you are in a cold climate and using the whipper in a high volume operation ice may block the inlet valve. We suggest alternating between two whippers so that the ice has time to melt.
The inlet valve is damaged - this part cannot be replaced unfortunately.
Why is gas escaping from where the head screws into the body? This is likely caused by a damaged or missing silicone head seal. These are available as a spare part on the website. It may also be caused by a damaged thread. Please inspect the thread of the head and the whipper regularly. If they are damaged you must stop using the whipper. Return to us and we will advise.
Why is no cream coming out of the whipper and no gas is coming out of the outlet (dispensing valve)? The outlet valve is likely to be blocked. Cream may have set in the valve blocking it. You should not use any solid ingredients with the whipper - granulated sugar or chocolate flakes for example will block the valve. You can easily dismantle the dispensing valve to clean it by taking off the head. However you must first release the pressure in the whipper by allowing the gas out. If the outlet dispensing valve is blocked you should unblock it first by unscrewing the nut holding the decorator on and then using a paper clip to poke a hole into the valve to allow the gas out - use the trigger to release the gas. Then push the valve out from the outlet side. Soak in warm water and clean using the cleaning brush that comes with the whipper.
Why is only gas coming out of the whipper? This is probably because the cream is too thick to be dispensed. Always use 'whipping cream' with your whipper. Double cream will set inside the whipper so this must not be used. Also if you shake the cream too much in the whipper it may set.
Why is the cream coming out too runny?
Make sure you are using whipping cream - single or double cream are not suitable.
If you are using whipping cream then you probably haven't shaken the whipper enough - please shake it vigorously about 6-8 times to thicken the cream. However if you shake the whipper too much (like 2 dozen times) you could thicken the cream so much it is too thick to be propelled out of the whipper!
