The hot water will not flow from the waterspout

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 the water pressure coming out of the steam/hot water arm is fine, then the issue is likely with the brew unit or the grinder. Here are a few things you can check:

1. Clean the brew unit: A dirty or clogged brew unit can slow down the flow of water. Remove the brew unit and clean it thoroughly, making sure to remove any coffee residue or buildup.
2. Check the grinder: A dull or clogged grinder can also slow down the flow of water. Make sure the grinder is set to the appropriate setting for your coffee beans and check that the grinder is not clogged.
3. Check the water flow meter: The water flow meter measures the amount of water flowing through the machine. If it is clogged or damaged, it can affect the flow of water. Try cleaning the water flow meter with a soft-bristled brush and see if that helps.
4. Check the water filter: If your machine has a water filter, it may be clogged and affecting the flow of water. Replace the filter if necessary.

If none of these solutions help, it may be a more serious issue and you may need to bring your machine to a professional for repair.

Unplug machine
Close both hot and cold water valves at the wall
Get a 5 gallon bucket, disconnect the hot water hose at the machine and place the end of the hose in the bucket
Slowly open the hot water valve to see that hot water flows through the hose
If no water flows from the hose:
close the valve, remove the hose from the valve and slowly open the valve to see that water comes out, if yes, check the hose for screens at both ends and clean or replace them, if no water came out of the valve, get a plumber
If water flows from the hose:
Check to see that it gets hot
If not hot get a plumber
If hot, close valve and check for a screen in the male port on the machine where the hose goes, clean or replace it..
If any screens were replaced or cleaned during this test, remove the cold water hose and do all the same to it, cleaning and or replacing them also, and then reconnect both hoses, open both valves, plug the machine in, and retest to see if you have hot water now
If still no hot, you may call a repair specialist or acquire a repair manual pdf online and test the water inlet solenoid, the water temp switch, and the timer
Note if it is the timer, placing it in a different cycle usually produces different results, so try that, if the solenoid you'll need the proper tools and the skill to disassemble and reassemble your machine, so you may want to call a repair tech

WATER OVER FLOW ERROR // Water continuing to enter machine
The manufacturer has assigned this error or fault code to indicate that the washer is overfilling due to a defective water inlet valve. The valve is not repairable and will need to be replaced.You can check it with a multimeter to confirm, it should show continuity on both hot and cold pins. try exchanging the how and cold water hoses, cold on hot and hot on cold, see what happens. have u tried running only cold water or hot water wash? as for the smell could be a build up of detergent or frabic softner, try washer running machine with hot water and vinigar to clean out also check inlet valve for dirt build up

Delonghi Perfecta won't froth milk or allow hot water to come out from waterspout

Put the temp select switch on HOT, start machine. If water comes out check the flow amount. If no water flow, replace inlet water valve. If there is water flow switch to COLD, start machine. If water comes out check the flow amount should be approximately equal or slightly more than flow on HOT. If no water flow, replace inlet water valve. Move selector to WARM, start machine. Now there should be twice the flow of water than there was with HOT and COLD temps. I suspect it is the HOT side of inlet water valve that has failed because machines usually rinse with COLD water.

Open the tap with frother spout off. This happened to mine and I took the frother tip off and opened tap with tip off. Water filled and I closed tap...Machine returned "Ready". I heated water in microwave for three minutes- placed frother tip in hot water and all kinds of gunk came out. Lesson learned- Do a thorough cleaning of frother by immersing it in very hot water at least once monthly- even if you don't use it
