At a loss. Have been in our house for 6 years. Gone through 3 brand new dishwashers. NEED APPLIANCE REPAIR OR PLUMBER. which we have had both. No one can figure out why dishwasher gets disgusting pink fungus. Hot water heater changed. Lines changed. Hot water running to it we are at a loss can't use we have a huge family and this is just ridiculous. No one knows how or what to do.
