Inconsistent Brewing on K70
I am trying to fix a K70. It will usually brew a cup once or twice, then stop brewing. Once it stops, it will make little to no noise and not pull water in. I've ruled out the one way check valve on the top. I also followed the steps to lube the vacuum pump diaphragm. If I unplug the Keurig, it seems to reset and will brew another cup once I plug it in. Any thoughts on what to try next? It seems like it could be a pump problem, but I'm not sure.
Is this a good question?
