Can NOT release the attachment
Had the same problem.
Spray Wd-40 or similar in there. Makes the O-rings work better. Soap and Sun and water makes the seals thirsty.

Always keep your Owners Manuals so you can use it to get parts. Without seeing it myself, the part will probably have to be replaced.Sometimes you can find the manufacturer online and get parts through their website.
