The ticking of the timer is so loud and can be heard on the other side of the wall inside the house. Is there any way to quiet the timer or do I need to just disconnect the whole thing to get rid of the annoying ticking? If I do need to disconnect the timer, how do I do so?

Water Heater Timers Save Money

1) Yes, the noise is from clock motor turning the gears.
When timer is new, parts have a bit of white grease on them.
Turn off power and spray WD 40 or apply some white grease and see if that helps.

2) Yes WG1573 240Volt clock motor is going bad.
Tip out mechanism using thumb spring located top inside box and check clock motor number.

Buy WG1573 240Volt clock motor and extra trippers from Granger number 1PNK2

Notice on image below, there is a bit of white grease on lever.

1) It depends on timer you have.
Intermatic-brand box timers used to control water heaters, outdoor signs, pool pumps and parking lot lights generally have replaceable clock motor.
paragon-brand clock motors are not available.
Tork-brand clock motors are more difficult to find, depending on model number.
In-wall timers & plug-in timers are not repairable, and you buy a new timer.

If I understand correctly you have 15 amp breaker with 14gauge wire.
Total watt capacity of 15 amp breaker is recommended at 80% rated load = 12 amps

You want to connect two appliances to same 15 amp line.
1) You have 6 amp Dishwasher that draws 720 Watts
2) You have under the counter water heater with 1500 Watt element that draws 12.5 amps.
3) Combined load is 18.5 Amps and 2220 Watts, approximately
So you do not want dishwasher and water heater turned on at same time.
Makes good sense.

Solutions:
> Easiest thing would be to put water heater on ordinary wall switch located inside sink cabinet.
Back when garbage disposals first came out, garbage disposal switch was inside sink cabinet. You opened cabine door and flipped the switch.
> Next solution would be to put water heater on a timer located under the sink. There are different timers. In-wall timers and box-type

In-wall timer would need relay/contactor
A battery operated timer like the ST01C would not need to be reset after power outage

Here are instruction pages for selecting and installing the relay/contactor.

Box-type timer like T101 120Volt timer. This timer needs no relay/contactor.
http://waterheatertimer.org/How-to-wire-T104-Intermatic-timer.html#T101
Timer needs to be reset after power outage, but operates on ordinary 120V power, and is simple to install.

> There is no easy way to wire the dishwasher and water heater together so one is certain not to operate when other is turned on. There are likely electronic control panels for that project. But since you know the hours when dishwasher is likely to be ON, then set water heater timer to turn OFF during those hours. Water inside tank will stay hot for a couple hours, so there is no loss.

It sounds like you are a solid electrician.
If needed, add comment any time for more assistance.

If you have Intermatic timer, then clock motors are available for most hard-wire box-type timers. Most pool and spa timer modules are available or have same/similar replacements. If you have plug-in timer, including power pack or portable outdoor timer or indoor plug-in or in-wall timer, then no clock motors are available.

If you have Tork timer, then clock motor is available for 1100 series.
http://waterheatertimer.org/Tork-timers-and-manuals.html
If you have Paragon timer, clock motors will be hard to find
http://waterheatertimer.org/Paragon-timers-and-manuals.html
If you have other brands of timer, then clock motors are not available except Deihl, DIGI and Grasslin timer modules, but post brand and model number of timer so I can search my files.

well that can be a problem the first thing you have to do is check for water leaks under the house or between the walls that can be one of the reasons why the heater is emptying so often, I can tell you that one time I had to fix a problem like that the guy was paying a lot in gas and the water line behind his bathroom sink (between the wall) was punctured a tiny hole but it was constant so he had to pay me to fix the leak and the roof and the walls on the apartment downstairs.
So most likely there is leak somewhere in your water line inside the house; before you pay a plumber try to find it yourself (so you don't have to pay for his time) if you do find it then call the plumber to fix it and check again.

if it works for you don't forget to rate me

thx

The gray timer box saves power by turning the power off and on to the water heater. Most that I have seen have a 1/4 inch screw head that you loosen and tighten to change the time it runs and shuts off. Basically operates like the outlet timers you use from a wall outlet.
Installed one for my mom over 25 years ago, still working.

We had the same problem - the hot water would only be hot for 3 -5 minutes and shut off, then we had to turn the water off, wait a few minutes, and do it again. VERY FRUSTRATING.

Soution: The Rinnai serviceman showed me the heat-exchanger blower/fan: It was clogged with dust and moths.

Another clue: Our Rinnai was extremely noisy when the heat came on. After the fan was cleaned and replaced, it is nearly silent.

If you are reasonably mechanically inclined:
TURN THE BREAKER / POWER OFF to the unit.

The blower-fan is located in the lower central area of the unit (at least on our unit). If you draw imaginary north-south, east-west lines through the center of the unit, the fan is in the lower-left quadrant. There is a spring clamp securing the black rubber accordian-like tube to the fan. There are two screws that secure the fan to the unit. there are two plugs that connect to the fan, as well as a third air-flow sensor that should be removed. then you can look at the fan unit, as well as the grill on the underside of the heat-exchanger that should be cleaned.

My thought was to go out and get a simple bug-screen, and place it over the air-input outlet vent going outside, but the repair guy said that although it may sound good, if that screen ever gets clogged, or reduces airflow to the Rinnai, then the unit will work harder, or even shut off, giving the same problem. Also - the Rinnai pipe going outside is a pipe within a pipe - so its both inlet and outlet air.

I've ended up with a Drayton Tempus 3 when I bought my house, and I think this is how it works. It allows you to set 2 Timers (I'll call them timer 1 and timer 2) so that you can control Hot Water or Heating On/Off times twice a day. The unit has 6 buttons - 2 for Adjustment, 2 for Hot Water and 2 for Heating. The 2 Adjustment buttons allow you adjust the Clock Time, or allow you to adjust Timer 1 and/or Timer 2. NOTE: Timer 1 is the time refered to on the Heating / Hot Water Select buttons if you press "Once". If you select "Twice" on these the both Timer 1 and Timer 2 are taken into account. For example if you want Hot Water to come on Once between 8pm -10pm, but you want Heating to come on Twice between 6am - 7am, and 8pm -10pm, you have to do the following: Set Timer 1 to 8pm - 10pm, and set Timer 2 to 6am -7pm. Then select Once for Hot Water, and select Twice for Heating. Hope this helps.
