Delonghi DR18T Timer Replacement

My Delonghi heater will not turn off and on in relation to what time the timer is set for. Works fine manually and with the thermostat. Any advice on how to replace the timer? Where can I find a repair manual for the heater.
Thanks,
Mike

    To be honest with you I can't figure out how to get the timer out. I see no way to access it. Any suggestions?

    Thanks,

Open up the front panel and get to the timer panel. if you can see a battery compartment, open it and replace the battery.

Before you replace the timer, check and see if the timer has a battery in it. if it has, then change the battery. it will work fine.

Hi i have a new DeLonghi Dragon 3 heater. The timer seems to work opposite to your instructions - i.e. the instructions indicate that the notches must be pushed to the outer ring to indicate the operating...


This is from the instruction manual online:

To set the heating periods proceed in the following manner:

- Check the time by your watch. Supposing it is 10.00 a.m. turn the numbered dial of the

time-clock in a clockwise direction until the number 10 coincides with the reference mark s

on the time-clock. Set the time period during which you wish the appliance to work by

pushing the notches towards the centre. Each notch corresponds to a period of 15 minutes.

At this point sections will be visible corresponding to the working periods.

Set in this way the radiator will function automatically every day during the set period.

(Important: the plug must remain connected to power supply).

- To change the programmed time period, just bring back the black notches to their original

position and set the new working periods required.

- If you wish the appliance to function without programmed working periods push all the notches

towards the centre. In this case, to turn the appliance off totally the plug must be pulled
out apart from switching off, so as to avoid unnecessary working of the timer.

Timer will not turn water heater ON at set time, has to be done manually. However, it will turn water heater OFF at set time.


If this is new installation, check wiring. Hot and Load wires might be reversed.
Check that ON OFF trippers are both attached to yellow dial.
http://waterheatertimer.org/How-to-wire-WH40.html

If timer worked fine before, and started missing recently, then tripper pins probably worn out.
Trippers contact mechanical lever, and push lever on-and-off.
Trippers are softer metal and designed to wear out before lever.
If lever is worn out, timer needs to be replaced, but try new trippers first.
Buy trippers at Grainger
http://www.grainger.com/Grainger/INTERMATIC-Timer-Tripper-2E054?Pid=search
http://www.grainger.com/Grainger/timer-accessories/timers/electrical/ecatalog/N-8hi

How WH40 timer works:
Clock motor rotates dial.
ON-OFF trippers on dial contact lever.
ON tripper pushes lever one direction.
OFF tripper pushes lever other direction.
Lever moves electrical contacts together, or pulls contacts apart.
When lever moves on-and-off, manual override lever also snaps back and forth with audible clicking sound.

Using q-tip, add touch of white grease to lever where trippers contact.

Delonghi dragon oil filled heater with timer. How does the timer work, is there a way to set it so that it stays on all the time? Do not have the manual


Within the timer is a 3 point switch. Push the switch to the end closest to the arrow and away from the clock icon. It will stay on

Clock Stopped Turning


Most likely, the timer motor has failed and needs to be replaced. As the timer motor is constantly running 24/7, getting 19 years of use is significant and is well beyond the typical life of a mechanical timer of this type. I know, I've got the same ones on my pool and usually have to replace them every 10-12 years.

As the timer IS 19+ years old, it would be best to replace the entire unit instead of looking to tyr to get just a replacement timer motor, since the cost for a new timer isn't all that much compared to the cost for just the motor.

Intermatic also makes a digital timer version of this type of timer, but for the relatively low price of a new, replacement mechanical timer, it might be a good idea to get another one like you have and expect another long working life.

Sorry that there really isn't much to repair in such an old timer, since the motor is the critical part.

The replacement should be easy to do yourself, just remember to turn off the power breaker and disconnect the power to the timer. All you need to do is exchange the wires into the new replacement timer I find that taking a picture of the timer as it is, will help you get the connections correct for the new timer.

Also, check the model number of your present timer and voltage, (some pool equipment is 100V-AC while others are 220V-AC) to get the correct replacment timer.

Hope you find this Very Helpful and best regards.

Delonghi Incredible heat machine can't turn off the timer.


Timer is set by moving the little black switches out over the orange ring. You may need to use a coin--but slide it so that if the orange ring is visible when looking at it dead-on (crouching down, obviously) then it's off at that time and vice-versa.
