How do I clean the filter

If the heating elements in your M-90 automatic coffee machine are functioning properly but the water is not being heated, there may be an issue with the water flow or temperature control system. Here are a few troubleshooting steps you can try:
1. Check the water reservoir: Ensure that the water reservoir is properly filled with clean water. If the reservoir is empty or low on water, the machine may not be able to produce hot water. Refill the reservoir to the appropriate level.
2. Clean the machine: Over time, mineral deposits can accumulate and clog the internal components of the coffee machine, including the water lines. Follow the manufacturer's instructions for cleaning and descaling the machine. Use a descaling solution or a mixture of vinegar and water to remove any buildup that could be obstructing the water flow.
3. Check the water filter: If your coffee machine has a water filter, make sure it is clean and not clogged. A clogged filter can impede the flow of water and affect the heating process. If necessary, replace the filter according to the manufacturer's instructions.
4. Inspect the water pump: The water pump is responsible for circulating water through the heating elements. If the pump is malfunctioning or not working at all, it can result in no hot water. Listen for any unusual noises coming from the machine while it's trying to pump water. If you suspect a problem with the water pump, it may need to be repaired or replaced by a professional technician.
5. Contact customer support: If none of the above steps resolve the issue, it's best to reach out to the manufacturer's customer support or contact a qualified technician who specializes in coffee machine repairs. They will be able to diagnose the problem more accurately and provide you with the necessary steps to fix it.
Remember to always refer to the user manual or contact the manufacturer for specific troubleshooting instructions tailored to your M-90 automatic coffee machine model.

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.

The F8 E1 code indicates a problem with the water coming into the washing machine for most Amana washing machines. This could indicate a problem with the inlet valve of the washer, the water hoses or your incoming water pressure. First make sure that the shut-off valves for the washer water lines are open. Close these valves and disconnect the water lines. Keep a bucket handy to catch the water in the hoses. Check the filters for debris and clean out any clogged filters. (Check both at the shut-off and the washer inlets.) Connect the hoses to the shut-off valves and check how much water flows into your bucket. (Some hoses are designed to limit flooding and restrict the flow when the hose is damaged. Replace the hoses if they are older or limiting your water flow.) Connect the hoses back to the washer.

Next do you get water flowing into the washer when you start the machine? If possible, try both a hot cycle and cold and check for different flow rates. (We had the inlet valve on a washer fail to provide full flow for hot water. Replacing the valve cured the problem.) Replace the valve, if it's not opening properly. If you are getting good water flow, you might have a problem with the water pressure/flow sensor. There could be dirt blocking air flow in the tubing to this sensor. Clean out the tubing or replace the sensor. The problem could also be with the wiring or the control board not getting the messages to and from the inlet valve or pressure sensor.

I hope this helps. The parts diagrams for the NTW4516FW2 are available from Sears Parts Direct: https://www.searspartsdirect.com/model/1l5hhsznio-001268/amana-ntw4516fw2-washer-parts .

(With the faulty inlet valve, we were able to improve the water flow temporarily. We took off the hot water line and filled it with household vinegar while turning on and off the washer. This dissolved the calcium carbonate deposits inside the valve.)

For Bosch and Neff washing machines, the F19 error means that the incoming water did not reach the desired temperature in the 'normal amount of time'. This could be due to a fault with the heating system, the sensor, or the communication between the sensor and the main control board.

The issue could also be due to insufficient hot water reaching the washer. Check that the inlet hose isn't kinked and that the hot water shut-off valve is open. Close the valve and remove the hose. Check and clean the filter at the washing machine inlet. Clean or replace the filter at the shut-off valve. Replace the hose only on the shut-off valve and place a bucket underneath it. Open the shut-off valve and check the water flow. Replace the hose if there is limited flow. (Some anti-flood hoses restrict the water pressure when they detect a small leak.) If you do not have good water flow with a new hose, check the flow from the valve itself. Replace the valve or fix other plumbing issues causing the restricted water flow.

If sufficient hot water is reaching the machine, then you have to find the fault in the heating system. If the washing machine is under warranty, contact the manufacturer. If you would like me to search for any available parts diagrams, please add a comment with the model number of the washer.

I hope this helps.

Turn of hot tap and disconnect hot water hose from inlet solenoid, using long nose pliers pull out filter from solenoid.
The problem may well be the solenoid needs replacing as they do tend to fail occasionally.

You might have crossover problem caused by bad faucet cartridge.

Factory temperature setting is usually default 120 degrees.

Thermostat calibration is always approximate.
120 degrees is not hot enough to burn the skin.
Exceptionally cold incoming water temperature can cause tankless not to heat enough hot water: install tempering tank to preheat water to room temperature.
Tankless cannot be exposed to more than 11 grains hardness in water. Delime tankless yearly, clean water filter monthly, do not install low-flow restrictions or conserve water since the flow rate must remain high for tankless to activate.

Hi just read your posting.The 2 lights that are flashing means your machine has not detected any water level difference.1st turn off both hot and cold taps and 1st remove the cold inlet hose from the machine end,Put the end of the hose into a bucket and turn the tap on.You should get a good flow of water.If you do not get a good flow of water then remove the tap end of the hose and see if you are getting water out of the tap.Check the inlet filters on both ends of the hose to see if they are blocked.If they are blocked clean them with a brush.Check also the water valve end where the hose connected to the machine to see if this filter is blocked. Once you have water coming out of the hose and all the filters are clean refit the hose and repeat to the hot hose.Now select a cycle and push start.If the water flow is good then the machine will work properly.If you still get slow water even when you have good pressure coming out of the hoses then your water valves are faulty.Please reply on how you got on and for further advice.looking forward to your reply.

Clogged/defective/burnt out hot water valve. Disconnect hot water hose and clean the filter in the valve inlet. If this did not help, check if there is power to the hot water valve when it's supposed to fill. If there is power, but no water is coming into the washer - replace the valve.

Hi

If your dishwasher is cleaning poorly, check these:

Water-inlet valve Most cleaning problems are caused by the dishwasher not getting enough wash water, so the water-inlet valve is often to blame. This valve is usually at the bottom left or right of the dishwasher, behind the lower access panel. It's the device with the main water line from the house, a rubber tube to the dishwasher, and two wires attached to it. 

When a water-inlet valve is defective, you may hear the sound that's usually referred to as "water hammer." If the water-inlet valve is defective, you need to completely replace it. 


Internal filters Every dishwasher has some type of filter to keep large food particles and foreign objects away from the pump assembly:

• Most modern dishwashers have self-cleaning filters that don't need any routine cleaning.



• Some have filters in the bottom of the dishwasher that you need to periodically clean. You don't need any tools to remove the filter, and cleaning it is easy. Consult your owner's manual to determine which type you have and its maintenance requirements.

If your filter is clogged, it may be causing the cleaning problem. 

Drain valve Some dishwashers have a valve (or gate) that should open only during draining. If debris lodges in the valve, it can't close properly, so water drains out during the wash cycle. Most dishwashers drain into the garbage disposer. If yours does that, listen for water flowing into the disposer during the wash cycle. If you can hear it then, the drain valve may be clogged.

Spray arms There's a spray arm at the bottom of your dishwasher--it may have a tall spray tube mounted to the center of it. There may also be a spray arm located directly beneath the upper rack of dishes and/or above the upper rack.

If debris is blocking the holes in the spray arms where the water comes out, it could cause cleaning problems. Regularly inspect each of the spray arms and clean out the holes as necessary. 

Water temperature To get the best cleaning results, the water entering your dishwasher needs to be hot enough. Try running the hot water in your kitchen sink for about 30 seconds before starting the dishwasher, to pre-heat it. Also, if your dishwasher lets you select a higher wash or rinse temperature, try that to see if it helps. 

To check the temperature of the hot water that comes from your kitchen faucet use a waterproof thermometer. If the water isn't 120 degrees Fahrenheit, your dishwasher may have trouble getting your dishes clean. You could increase the temperature of the hot water to the whole house--and therefore the dishwasher--by adjusting the hot water heater thermostat.

Warning! To lessen the risk of scalding, don't set the hot water heater temperature higher than 120 degrees Fahrenheit. 

Detergent cup Dishwashers don't perform their best if detergent is introduced only at the beginning of a cycle, so add detergent to both parts of the cup.

I see the same problem and now that I know it's a water temp sensor, I really don't have a problem. Living in Houston it get's so hot the cold water is hot coming through the pipes. I didn't have this error 24 until summer...
