My sunbeam em5600 coffee machine isn't working. It's worked unreliably but now it seems to be consistently not working. Plenty of water comes from the showerhead when there's no group handle in. I am able to get steam from the steamer but it runs out of steam quickly. I can't get any hot water stream from the steam wand.
When I put a single basket in the group handle it works. When I put fine or coarse or nothing in the double basket nothing comes out anymore. I have occasionally seen a drop of water coming out over the top when the group handle is in but nothing more so I don't think it's the rubber ring. When I take the group handle out after a failed attempt there is a squeak noise so there definitely water built up under some sort of pressure. I soaked the baskets in vinegar for at least 12 hours last night, didn't help. I cleaned the machine every few months which is far more often than what the manual recommends.
For as long as I've had the machine which I got used I find the large water reserve can't fall below half for the machine to work.
I do tend to aim for a very fine espresso grind, but it works in the single basket. My grounds have never formed the hard biscuit that you get when using professional machines.
Is there a simple fix here like a new ring or basket or is it the water pump? If so how hard would it be to replace on my own?
