LOWES TROY-BILT PRESSURE WASHER MOTOR GONE BAD Prince George Virginia

I purchased a TroyBilt pressure washer with a Honda motor thinking  this was a reliable equipment choice and paid the extra for the extended warranty,This was purchased on 5-19-2014.It has been used for about an hour a week cleaning concrete.The motor wouldn't start on 8-15-15 and was taken to Lowes on 8-19-15 for them to service.I received a call from them on 8-28-15 saying that the service tech stated that the cylinder walls were scarred and it was not worth repairing.They also stated that this wasnot due to a product defect.Lowes indicated that this is a grey area and the warranty would not cover this.This unit was used solely residental use and never more than a hour a week.This is still in arbitration and hopefully Lowes will do the right thing.
