In October 2017, I bought the WESTINGHOUSE Tankless Water Heater model WGRTNG199. Until now, the device worked without problems, however, for some time during the bath ceases to fly hot water. At the beginning, everything is fine and after about 3 to 5 minutes, the water becomes cold and in order for the collapse to fly hot I have to turn it off, wait a minute or two and turn it on again. It's quite tedious. I will immediately anticipate your question about the appearance of an error message. No, I did not notice any errors on the device. What could be the reason for this? I would also like to ask where is the guarantee service closest to my place of residence? I will mention that I live in Ludlow, MA zip code 01056. Another question, how long will I have to wait for it to appear in my home service and remove the defect. I look forward to your prompt reply.

I had same thing happen with a unit I purchased in October 2017 and the Tech Support telephone number was no help. The water became cold while taking shower. The unit had error code 11 and 67 at startup when restarted since the blue device with a knob couldn't turn according the tech support which I starting calling the anti-tech support department. I personally like hot water for the dishwasher, washing machine and shower. I bought a power vent 40 gallon tank water heater and replaced the Westinghouse MTP ANTI-water heater since the anti-tech department couldn't help resolve and apparently doesn't care that I didn't have hot water. Get a new tank type water heater that isn't Westinghouse or MTP or whatever they are?
