Hi, my name is XXXXX XXXXX I have been in the home improvement and repair field for 20 years. I will be very glad to help you today. Is the float sticking? If you check the float in the bottom the float may be hung up. Also is it humming or making any noises?
i cannot determine the float which i feel must be stuck as you suggest. the machine is humming
More likely we are dealing with a blockage in the pump if it is humming then. If you first look at the drain connection at the sink does the drain look to be clear? You may have to disconnect it to be sure.
sorted thankyou very much
You are very welcome.
