Make sure the supply valve that feeds the dishwasher is turned on. If it comes back, it needs a visit. ### Is H2O on my Maytag a reminder about water hardness? No, Maytag uses those letters to say the tub stayed dry when the machine asked for water. It is a supply issue, not a maintenance prompt. ### Will my Maytag carry on after H2O once water is back? Yes, restore the supply and press Start; the machine attempts the fill again and continues the cycle. A repeat with the valve open and the hose straight calls for a visit. --- **[Read on the site: Maytag dishwasher showing H2O | DishwasherRepair.center](https://dishwasherrepair.center/error-codes/maytag-h2o/)** **[Book a visit with DishwasherRepair.center](https://dishwasherrepair.center/schedule/)**
