One year old Whirlpool Frontload Washer problems?

Sounds like your problem is with the washer itself and most likely has nothing to do with the pipes. If the washer is only one year old, it is probably still under warranty. If it is still under warranty you need to call the company and have them get a service tec out and get it repaired before the warranty expires. Your best bet would be not to try and do anything to it because it would cause the warranty to be voided. I am not telling you not to advise the company of you putting vinegar in the machine, however I will say this. Usually anytime you try and do anything to or put anything into an appliance like a washer it will almost always void the warranty since it is something they probably do not recommend. Now, that being said, you will have to decide if you really want to advise them of the vinegar or anything else you might have done to it. As for the pipes, sounds like there are blockages and if so, all the pipes need to be cleaned out and flushed out. If not done you will most likely be calling them back to clean out another one which in turn will cost you a service charge each time they have to come out. It is possible the timer switch or whatever it is referred to now days is bad and not telling the machine to do what it is suppose to. That will have to be done by someone who knows out to test the circuit to see where the problem is.
