After extensive searching there is no procedure shown. Presumably, you leave it, or you remove it from the installation, turn it upside down and shake it. Then put CLR and water in it to descale it, then rinse and reinstall. Hot water storage tanks have a drain at the bottom and an access hole from the element. After a year of use there should be nothing in it. You could phone the maker / distributor and ask? https://www.google.com/search?q=Little+Gourmet+Instant+hot+water+dispenser+clean+out+the+sediment ..

Energy smart water heater has start up failure problem so how to resolve

The OHL is not for sale due to a couple of reasons. If the heat exchanger has a hot spot it will melt the OHL making it useless. The OHL is just a large fuse. Rheem will completely warranty (if within date range) if the OHL or heat exchanger has problems. Bypassing the OHL is very dangerous and could result in a house fire since the appliance is mounted to a wall. I would suggest scrapping the copper heat exchanger for cash. That about all its worth in the condition its in.

For a Noritz tankless water heater, error number 78 indicates a problem with the fan motor. The instructions below will help you clear the problem number 78 on a Noritz tankless water heater:

1. Turn off the power to the tankless water heater by either disconnecting it or switching off the circuit breaker.
2. Verify that the fan motor is clear of any obstructions or debris that may be preventing it from operating properly.
3. Check the fan motor is receiving power by measuring the voltage across the fan leads with a voltmeter. Verify that the electrical connections to the fan motor are secure if there is no voltage.
4. If the fan motor is broken or not operating properly, it may need to be replaced. For further assistance with the repair or replacement of the fan motor, you can contact Noritz technical support or a certified HVAC specialist.
5. After resolving the issue with the fan motor, switch off the power to the tankless water heater for at least 30 seconds before turning it back on. This will clear the error code and restore normal operation to the device.
6. If you are unclear or uncomfortable with any of these processes, you should seek the aid of a certified HVAC specialist or Noritz technical support.

Check the thermocouple and the control box.

It's possible that the sequencer needs to be replaced, as it's responsible for turning on and off the different heating elements in a certain sequence. However, it's also possible that the issue could be with another component, such as the high limit switch or a faulty heating element. It would be best to have a qualified technician diagnose and troubleshoot the issue to determine the root cause and recommend the appropriate solution.

There are several potential causes of low water pressure with a tankless water heater like the Tempra 24 Plus:

1. Flow rate limitations: Tankless water heaters require a minimum flow rate to operate properly, typically around 0.5-0.6 gallons per minute (GPM). If the flow rate drops below this threshold, the heater may shut off or fail to produce hot water. In your case, the initial flow rate of 3.4 GPM is well above this minimum, but the drop to 1.6 GPM suggests that there may be a flow restriction or other issue causing the lower pressure.
2. Water supply issues: Low water pressure can also be caused by problems with the water supply itself, such as a clogged or damaged pipe, a water main break, or problems with the city water system. Check with your local water utility to see if there are any known issues or maintenance activities that could be affecting water pressure in your area.
3. Water filter or softener issues: The whole-house water filter and softener that you installed could also be causing low water pressure if they are clogged or not functioning properly. Check to make sure that the filters are clean and that the softener is operating correctly.
4. Plumbing issues: There could be issues with the plumbing in your home, such as a clogged or damaged pipe, a faulty pressure regulator, or incorrect pipe sizing. Have a licensed plumber inspect your plumbing system to identify any potential issues.

If you have already checked for these potential causes and are still experiencing low water pressure with your Tempra 24 Plus, it may be helpful to contact the manufacturer or a licensed technician for further assistance.

If your Bosch Highflow 21e hot water system is experiencing fluctuations in water temperature while showering, it could be caused by a few different factors. Here are some possible reasons for this issue:

1. Flow rate too high: The hot water system may not be able to keep up with the demand if the showerhead or tap is allowing too much water to flow through. This can cause the water temperature to drop suddenly. Try reducing the flow rate by turning down the tap or using a low-flow showerhead.
2. Water pressure fluctuations: If the water pressure in your home fluctuates, it can cause the hot water temperature to vary. This can be caused by various factors, such as other appliances using water at the same time, or changes in municipal water supply pressure. Installing a pressure regulator or a flow restrictor may help to stabilize water pressure.
3. Blocked or dirty water filter: A clogged or dirty water filter in the hot water system can restrict water flow, causing the water temperature to fluctuate. Check the filter and clean or replace it if necessary.
4. Malfunctioning thermostatic mixing valve: The thermostatic mixing valve (TMV) regulates the water temperature in the hot water system. If it's faulty or dirty, it can cause temperature fluctuations. A licensed plumber or technician can inspect the valve and replace it if necessary.
5. Faulty temperature sensor or control board: If the temperature sensor or control board in the hot water system is faulty, it may not be able to maintain a consistent water temperature. A technician can diagnose the issue and repair or replace the faulty component.

If you're unsure about how to diagnose or fix the issue with your hot water system, it's best to contact a licensed plumber or technician for assistance.
