Need to know and fix my black decker coffee pot will not brew

SOURCE: Black & Decker TCM700 Coffee Maker problem

the concept still applies. the heating element is usually dual functional. heating the water then keeping the plate warm.

There are two heat stages in the Spacesaver. One is the carafe heater you can see while the other is an assembly within the main housing. This assembly contains a heater, thermostat, and a section of metal tubing with high temperature silicon connectors at each end. when the water storage tank is inserted it fills the heated section of the tube and when activated the water boils as it passes through the one way valve and forces the water into the coffee container. This steam driven surge repeats until all water has been moved to carafe. There are several failure modes associated with this assembly an I have two. 1. is the heater opening which I have and 2. is the thermostat degrading causing incomplete transfer and ultimately no transfer because it brings the temp down prematurely. Another is crud on the check valve so many problems - no solutions

Try running a cupfull of vinegar through it followed by a pot of plain water.This will remove any hard water deposits which may be blocking the tubes.

SOURCE: my black and decker coffee maker will not turn on to brew coffee

All coffee-makers are provided with a thermal fuse located near the heating element and in series with the element itself.

This device is bullet-shaped with one lead connected to the case, the other insulated from it.

If there was no protection of this kind, it could lead to a fire if the heating element fails to get turned off when reaching its design temperature and nearly impossible to buy as a replacement part.

These are not user replaceable and both the thermal fuse and the bimetal switch that controls the current for the heating element have become increasingly less reliable as they are made in China and since we have little alternative, we have to either keep track of our warranty or just throw it away when it fails.

The fuses can fail at any time and I have brought back three coffee-makers in a five day period, all with the same failure, before giving up and getting a refund.

Another type of failure, namely of the bimetal switch occurs over time and reveals itself by the ever-longer brew time that is unaffected by dissolving the lime in the system.

The heat sensitive metal switch part becomes gradually less responsive causing the machine to just cough instead of pump as when new.

The last one I tossed had reached 40+ minutes per pot.
