Error code
Frigidaire-built Kenmore dishwasher signal Hd
Hd is an indicator rather than an error. Frigidaire publishes it for the dishwasher this badge covers, and it means: Frigidaire's own wording: the machine is in heat delay or heater on mode, waiting for the water to reach temperature.
- From $95 diagnostic, credited to the repair
- 59 cities and neighborhoods covered
- OEM parts available on order
- In writing the price, before anything is opened
What we can confirm
Signal Hd, from the manufacturer's own documentation
This code has no number, because this equipment has no display to put one on. The appliance signals it instead — an alarm, a symbol or a pattern of lights — and what it means is recorded in the documentation that ships with it.

The symptom this code usually arrives with
A code names the subsystem; the symptom is what sent you to look at the display in the first place. That page says what it usually turns out to be, cheapest cause first.

A full cycle later and the load comes out dirty Dishwasher not cleaning
On South Florida water a good share of these are chemistry and temperature rather than a failed component. The useful distinction is what is left on the dishes: grit is one story, film is a completely different one, and they lead to different places.
- Grit and film are two different problems
- Water temperature is measured, not assumed
- Hard water is a real factor here

What else belongs to the dishwashers
On this make a code belongs to the appliance rather than to a product line. These are the other conditions this machine can display, and the models that can show this one — a display often has more than one thing to say, and the model number decides what any of it costs to put right.

About Frigidaire-built Kenmore dishwasher signal Hd
Whose code this actually is
Kenmore did not write Hd, because Kenmore has never built an appliance. This one is Frigidaire's, and it appears on the dishwasher that Frigidaire built and Sears sold under the Kenmore badge. Whirlpool, Frigidaire and Bosch all built dishwashers for this badge, and their numbering overlaps enough to be convincing while meaning entirely different things.
What the appliance is telling you
Frigidaire's own wording: the machine is in heat delay or heater on mode, waiting for the water to reach temperature.
This one is an indicator rather than an error. It is published in the same table as genuine problems, and treating it as one is how a working appliance gets a service call.
Which Kenmore models can raise it
The Kenmore dishwasher whose model number begins 587 — the three digits before the period on the rating plate. Those digits are Frigidaire's, which is why Frigidaire's table is the one that applies to Hd and no other manufacturer's does.
The other ways it may be written
The same condition is published under more than one label, because it has been carried across generations of the appliance and because a segment display draws some characters oddly: HO. They are the same finding and they lead to the same place.
Worth trying yourself, in this order
- Nothing to do. This is the machine being patient rather than being broken.
- A machine that sits in heat delay forever is a heater or a thermostat, and that one is worth a call.
Where this usually goes
The job this most often becomes is dishwasher wash performance service, and that page carries a starting figure and the reasons that move it. A Kenmore dishwasher on this water scales its heater and its spray arms faster than the manual assumes, so codes about temperature and wash performance are read here with the supply in mind first. Photograph the display before you cut the power: a reset clears Hd, and on a Kenmore the characters plus three digits off the plate are most of the diagnosis.
Where this meaning came from
Frigidaire's own documentation: Dishwasher Error Codes and Alarms Guide, Frigidaire owner support. Kenmore publishes none of its own, which is why every entry on this site names the manufacturer's document instead.
