Mike, as nobody else has given a solution and I am not familiar with this particular model check if its a pump that delivers the water or is it gravity flow to a container in the bottom, if its gravity i have found the hoover candy machines to clog in the valve right in at the back, this would need removal and the area around it needs thorough cleaning, if its pumped find the pump remove it and test it with a mains supply sludge can easily clog them.your machine by description seems similar to the Hotpoint/creda range and i have found fans coming loose on the shaft, fiitng these its fan on the shaft with circlip near you, hope this helps
