Question: Does your heating element make a loud "snap" (sounds like an electrical arc) intermittently when the warming plate is on? Or did I get a faulty unit?
Document: I had this coffee maker for 7 months. I really liked the look and convenience of the grind n brew and had good luck with Cuisinart brand coffee makers in the past but not this one. Same story as some of the other reviewers in that "burning wire" electrical smell permeated the house one morning after the coffee was finished brewing. The following day I tried unplugging and re-plugging the machine in and the warming plate stayed cold and water would not pump.
Gets a star because you have to give one. And we wanted to love this coffee maker.First unit, the grinder died, worked for about 1 month. We then reverted to using it manually, grinding the beans ourselves. After a couple of weeks, the heating element died and we couldn't even make coffee. Fun way to wake up right? Because it was a Christmas gift, the time between purchase and using made it impossible to return to Amazon.
Loved this machine for 1.5 years until today. Apparently the heating element shorted out and filled the house with a horrible electrical burning smell. Definitely glad I figured out what was going on before anything really bad happened though.
I have used this every day for the past month and love it! I even bring my coffee from home to work now. I have not had any issues so far with the grinder or heating element. I love setting it for auto brew on those early mornings. Yes, the grinder is loud, but it doesn't bother my family. I would recommend it to everyone that loves good, fresh, coffee.
I chose the glass carafe w/ warming plate over the stainless thermal carafe because I didn't want to have to pre-heat the thermal carafe and feared it might not make hot enough coffee without that extra step. I've been very happy with the glass version... the coffee temperature is great - nice and hot - right after brewing. I don't let it sit too long on the burner (&lt;20 min.
The burr grinder still functions but for some reason the pump and warming plate no longer function. I called the company hoping to get some assistance. Following their instructions, I unplugged the machine for an hour and filled with a mix of water and vinegar. I plugged the machine back in and turned it on with no luck. I called the company back only to find they do not repair broken coffee makers outside of warranty. I was willing to pay to get it fixed.
This was the number one rated grind and brew in consumers reports back when it first came out and was the new fad (grind and brew was a fad then). My wife and I love the coffee so much more when fresh ground, and it was a loyal morning partner for many years. The heating element went out on our original unit, and I was looking for whatever is now the best.
The inexpensive Mr. Coffee unit I replaced with this one had a temperature control for the carafe's heating element. Can't imagine why this unit - which costs 4 times as much - does not. IMHO, consumer coffemaker carafe elements are set too high, and tend to 'cook' the last cup or so of coffee, rendering it less flavorful than the first; this unit is no exception. Also, for the price, one might hope to have a back-lit clock/selector, as my previous unit did.
This operated sufficiently for the 3 months I have had it. It lasted just long enough to prevent return to Amazon. Tried to make coffee one morning, it ground the beans....and then nothing. Heating plate is cold, water not pumping through, it's completely dead. Cuisinart's genius level customer service team advised me to unplug it and try again. When that didn't work...unplug it and try again.
We have purchased this brand and model for sometime, they just don't last. You would think this brand would be the best and with all the problems with it we still purchase it...something wrong with this picture I think??? We like the convience of it with the fresh brew and grind, timer,etc. We are now waiting for a warrenty one to arrive to replace the last one we had. The heating plate just caught on fire one morning.
Answer: I have not heard any type of unexpected noise froml the warming plate. if the sound you are hearing occurs after/during warming plate heat up, it may not be electrical in nature, but more of a thermal stress release. It this is the case then you can probably feel the movement byhaving your hand on the chassis during the noise event?  I am an electrical engineer and if I suspected an electrical arc I would verify it with an AM radio. At the same time of the noise listen to the radio for a corresponding pop in the speaker. Have either an AM standard broadcast or CB radio tuned to a weak or no signal with volume turned up. Sorry if this is a lot more info than you are wanting.
