Blak & Decker Home Cafe GT300 won't stop untill water is gone

With the GT300 you can service the unit. You will need a flat head screwdriver, preferably a low quality one, that will need to have a small spot filed out in the very middle of the flat head area to remove a few special screws that are common to these appliances.Luckily it is very easy to modify a flat head screw driver to remove the area necessary to make the tool work well enough to remove the special screws. After that, you will need a phillips screw driver as well. Remove all the screws, some are hidden underneath the plastic grip pads on the bottom as well. You will observer a tin can heater, and a priming pump (white) and an invensys ******** pump (red). The invensys pump (CP1, CL1) is very easy to service and this is what you will find the problem is 99% of the time. Just unscrew the plastic ends (you may need a wrench) on the invensys pump. It will come apart, be careful to keep all the pieces, they will spring apart like a jack in the box if you are not careful. Get all the pump pieces where they are moving again and then put the pump back together. There should be two metal rings with a plastic ring between them. You may have to plug and unplug the unit a few times and get out any excess water before getting the system primed and running again.

Unfortunately, the unit can't be repaired or fixed with any type of troubleshooting. It has a one year warranty from the date of purchase. If you've had it for a few years, off to the landfill it goes. . .
