remove drawer ,don't be afraid of giving it a good yank. look up at the top inside the machine ,you will see lots of tiny holes ,looks a bit like holes of shower head . use old tooth brush not your husband's lol to unblock holes due to build up of scum ,give drawer a good clean with warm soapy water ,refit ,probably need a bit of a shove to get it past locators ,should be ok now . hope this helps,.
