What makes this entry useful is the arithmetic this maker prints beside it — a minute or two of waiting buys a single degree. Do that sum on a machine plumbed twenty feet down a cold run and half an hour on Hd stops looking like a failure. Where a remedy exists it lives outside the appliance entirely, in how warm the line already is when the cycle begins. ### The other ways this one is printed Hd / HO · Hd · HO · H0 The same condition is printed differently on different panels of the same make, and every spelling the maker publishes for it is above. Whichever of them you searched for, this is the right page. ### Where this appears, and why not to clear it On the appliance’s own display, as a short single code — a letter and a number, or two letters. Nothing alternates and nothing arrives in halves on this make, so what the panel shows is the whole of it. Photograph it before you cut the power. This maker’s own answer to most of these is thirty seconds at the breaker, and that is worth following once — but a display that has been cleared has taken the evidence with it, and there is no way to ask the machine for it again. ### What to do about it - Draw the kitchen tap until it runs properly hot, then press start. The machine shares that line and begins the cycle from a warmer place. - Expect the delay to be long in winter and after a holiday — the colder the supply, the longer it sits, at the maker’s own one-to-two minutes per degree. - Check the cycle you chose. Sanitizing and heavy cycles ask for higher temperatures and wait longer by design. - If Hd never clears at all and the water never warms, the heater or its thermostat has failed, and that is a repair rather than a wait. ### Where this goes next The job this usually becomes is [diagnostic visit](/services/diagnostic-visit/), and that page carries a starting figure and the reasons that move it. If it turns out to be nothing — and on this make a real share of these are modes, reminders and settings rather than problems — the visit ends there and you pay the diagnostic and nothing else, or call [(305) 912-9018](tel:+13059129018) and describe what the panel is doing before booking anything. Error Code Hd or HO indicates the unit is in the "Heat Delay" or "Heater On" mode. This delay is to allow the dishwasher to heat the water to the optimal temperature for best performance. NOTE: The colder the water is, the longer the delay time will take to heat the water to the proper temperature. This normally is approximately 1 to 2 min. for each degree in temperature rise.
