This is a complex problem. 1. remove, check and clean brewhead (round screen above portafilter where water comes out); it can become clogged with gunk. 2. brewhead gasket may be old or damaged, they can be purchased on eBay. 3. brewing basket may have become clogged, I don't know if running cleaner solution through it will help, may have to replace it. 4. Likeliest source of problem is coffee ground too fine and/or tamped down too hard. These are not professional level machines and cannot work with very fine grind or heavy tamping. Try a coarser grind and a light tamp with the larger brew basket. Coffee must be ground with good quality burr grinder for correct consistency.

The lenses unscrew anti-clockwise, but they can be very stiff and difficult to grip. The best advice I can give you is to double or triple wrap a thick elastic-band around the lens as this will give you much better grip than you will get on the glass alone.
If you are still unable to unscrew the lens, squirt a small amount of WD40 / penetrating fluid down the back of the lens so it runs onto the threads and leave it for 15-20 minutes then try again with the elastic-band grip. Once the lens moves a small amount it will unscrew relatively easily. The constant heating and cooling of the oven causes them to lock.
Please switch off the power supply to the oven before replacing the bulb and make sure you have clean hands when replacing the bulb - grease from your fingers can cause the bulb to fail or shorten its life considerably.
Hope this helps. If you are still unable to unscrew the lens, please let me know.
I had the same problem when I started using the Sirena. When I put the portafilter on I was lining it up with the arrow. I found that if I tighten the portafilter on all the way to the right (past the arrow) it works perfect, no water spraying.
anyone else w/ this problem: cheap workmanship = cheap, malfunctioning machine. turn it upside down, unscrew the 4 screws w/ metal washers and the six screws with out washers from the base of the housing. once removed, you can see that cheap metal clamps are used around the plastic hoses which supply water from resevoir to steamer & brewhead via the pump. either length of hose above pump or below pump has come loose or pump is fauly or there is a hole in a tube. good luck!
