I have a problem with my Mr. Coffee (model prx33) coffeemaker. The
other day my wife ran vinegar water through the machine to clean out
any build up. This is a recommended regular procedure. After doing
this, the machine would not work. While the lights on the display
came on, water would not run through the machine to make coffee.
Additionally, the heating plate did not seem to get hot.
I opened the unit up to look for the thermal resistor. I checked for
continuity through the resistor and found that current flowed through
it. I assume that this test would indicate that the resistor is good.
What else should I try? Is there some place on the web that will
indicate a step-by-step procedure that I could follow in diagnosing
Thanks, Al Kondo
What is the resistor spec in ohms? Is it marked or have colored bands?
Check for resistance and compare to spec. Or save yourself the
trouble and spend the $30 on a new machine. They're pretty much
disposable these days. What is your time worth if it takes 8 hours to
trouble shoot and fix? For that much you could probably afford one of
those fancy espresso/cappucino models.
According to the manual there is a temperature control knob. It may
have been turned all the way down. I have also seen other coffe makers
that won't work unless the flashing 12:00 is set to a time.
No matter what happens, someone will find a way to take it too
Frankly if you have to open it up, a Mr. Coffee is not worth the
trouble. The are designed to be inexpensive to produce as a throw-a-way.
badgoffer did offer a good suggestion however, and that dies not require
opening it up.
This applies to scale on my kettle. There is a heavy buildup of that
stuff on the heating coils. I'd prefer not to use vinegar because its
not effective and the cost of vinegar will probably be more than a
replacement kettle by the time the loss of efficiency becomes
significant. On one occasion the kettle boiled dry and I added water
before it fully cooled. The scale buildup cracked. The scale debris
messed up my cup of tea. I have been using this dry heat procedure to
remove scale since.
My mr coffee costs 19.95 at kmart and it has been working like a dream for
years. No controls, just an "on" button. I love it, simple as hell, and
makes excellent coffee - also noted as a best buy by Consumer Reports.
Given the price, if the machine so much as hiccups, I buy a new one.......
