the first few went well for me as well,then it stuck and I was affairs to put a lot of pressure on the canister. Been looking for new canister in case this one breaks. Anybody know where to start! Called a dealer several times but no answer with covI’d-19 going on closest one to me is in Louisiana and the are on lock down. If there’s a dealer out there that can help let me know and maybe we can get together some how!I just did mine last weekend.. Same thing... THe first few changes it popped right out.. this time I had to pry it out with a screwdriver.
