My Estro is not feeling well. Pumps plenty of water at high pressure out of wand but no steam - just very hot water. VERY low pressure for the portafilter. When portafilter is off machine water pumps in a lazy manner, gets hot as it has for years. Are these symptoms of a clogged boiler? Lack of steam tells me perhaps boiler is jammed. Help. Thanks.

My Estro model has very low pressure - wand give hot water at high speed but no steam. Heater light comes on and hot water is pumped at pressure barely able to make coffee drip out of portafilter. Is this symptomatic of a clogged boiler or a failing pump? Pump grinds away and will pump out tank quickly through wand. Clogged boiler?
