HHH shows in the window. Won't start. What is the problem

corn syrup

It is probably the DDR memory...You may need to replace it with new one.

1- DELAY TIMER HAS A SWITCH FUNCTION THAT HAS FAILED. 2- WASH INSIDE OF BREAD MAKER WITH COLD WATER, DRY, AND TRY TO SET TIMER. 3- BREAD MAKERS ARE NOT AS POPULAR AS THEY USE TO BE, AND ARE AVAILABLE AT USED ITEM STORES FOR 15 TO 25 DOLLARS.

I don't think it is compatible with Windows XP. Try it with a newer version of Windows. ie. Windows 7 or newer.

You need to let your machine cool off before baking a second loaf.

Possibly the booster thermostat needs replacing. Expansion of the water in booster enters the wash tank when boiling showing HHH on both displays.

That just means that your the oven chamber is too hot from the last loaf you baked in it. It does that because the ingredients have to be at at the correct starting temperature or you won't get a good rise. It's designed to do that.

However, ifIf you have let your machine cool off (open the lid and leave it open after baking for about half an hour) and still shows the HHH then you have a more serious problem and should call or contact Sunbeam.

Generally, an HHH error code means the machine is sitll too hot from making the previous loaf. Keep the door open for a bit and allow it to cool down.
