2001 u320 bladder will not de flare what too check
thanks fred
Fred' you may know most of this
reset the HWH, whether at the HWH panel or by cycling the 12 Volt master switch is the transmission in neutral and the engine running, and is air up on the coach? Best if the coach engine is running. (it could be your 12V compressor is not working) Shut off the slide room switch and cycle again, the bladder is on a timer, I believe on that model and should start to deflate pretty fast it will deflate faster with the engine running, as the compressor on the coach will make more volume air than the one on your 12V compressor - in either case the bladder needs a source of compressed air to deflate
