I have a P5000 serial Nr AT3500810 that wont start and shows code E38 - which i understand is vapouriser failure. When i bought it yesterday it had a massive leak at rear cover plate of vapouriser so i got a new rubber diaphram gasket for the cover and retried starting it now the carb seems to freeze up and propane sounds like its rushing into carb. My question is whether i should purchase a new 800 dollar vapouriser or if there is any info that someone could share with me in order to repair this machine.If i dissassemble the vapouriser is there anything i should be looking for? Thanks in advance
