Red light's on... but no hot water!

Question edited for typo 'not' to 'hot'.
Question moved from Washing Machines category.
Having the model number is useful in these questions.

According to this, a red flashing light means the water is heating. If it never goes to steady red, it may indicate that the heating element may have failed.

HI,

OK, inside the unit there are three items, the heating element, thermostat, and thermal fuse.What has happened is the element got too hot and the thermal fuse opened.There is no reset button.In some cases you may run across a defective heating element or thermostat but its not common.The fix would probably be replacement of the thermostat and thermal fuse.For this, you would have to contact a small appliance repair center in your area.

Goodluck,
Please don't forget to rate the solution

Not sure about modern heaters with lots of lights but inside there is usually a pressure switch that prevents operation if the water pressure falls and a temperature switch that cuts the power if the temperature rises too high - in a single heat unit there are only two wires supplying the heater element and the temperature is controlled by the water flow. It is straightforward to use an ohmmeter to check the element but with a multi-heat unit there is likely to be a switch to contend with and several connections to the heating element.
In this case it is a good idea to draw out the circuit so it makes more sense - if the element tests ok, it is likely one or the other of the safety switches is faulty.

While it could be many things that have gone wrong, the most likely cause is the heating element has failed. Call the local dealer.

red light shows when power is applied to elements, and water is heating

Heating Element

If lights are flashing on the control panel, the heating element might have burned out. The heating element heats the water up to operating temperature. After a set amount of time if the temperature isn't reached a light on the control panel might start flashing. The heating element can be checked for continuity with an Ohm meter.

Heating Element Assembly

If lights are flashing on the control panel, the heating element assembly might have burned out. The heating element assembly heats the water up to operating temperature. After a set amount of time if the temperature isn't reached a light on the control panel might start flashing. The heating element assembly can be checked for continuity with an Ohm meter.

Check Fault Codes

If the display lights are flashing and there is an error code in the display window, check the wiring diagram and tech sheet in the dishwasher that will provide information on the fault.

Drain Pump

If lights are flashing on the control panel, the drain pump might not be working properly. For two-wire drain pump motors check them for continuity using an Ohm meter. If it's defective You'll need to replace it. Drain pumps are not repairable.

Touchpad and Control Panel

If the lights are flashing on the display the entire touchpad and control panel assembly might be defective. If the display works but the dishwasher functions are all out of synch, or some of the buttons don't respond properly the entire touchpad and control panel might need to be replaced.

Touchpad

If the display lights are flickering for no reason, the touchpad might need to be replaced. Sometimes when the touchpad is defective the display lights are flashing randomly.

What is the model or year?

Broken drive belt my friend.

This will be a thermostat or element problem. The red light tells us that you have power to the unit. If you are handy you can test the thermostat and the element with a continuity tester. A voltmeter may also be used. This will tell you where the fault lies.

Yeh,
I ve seen this before.
Try turning on one buner at a time. Make the element red hot!. If one does not get red hot. make a note of that switch.
Some stoves create a way for a technician to know which switch is shorted and uaually it is the one that doesn't get red hot.
If all buners are red hot , preheat oven for 350 and wait. it should take 5min to heat up oven. if oven not hot ,one of the elements is blown
