Low Water pressure from the unfiltered spout on the Pur wat?r filter rf-9999. Plenty of pressure in the line.

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.

The FT-840 uses a die-cast RF power amp with thermally switched fan to ensure full power output (up to 100 watts). The digitally synthesized local signals ensure clean, low-noise transmitter output on all HF amateur band. There might be no AC line interference. it has strong Rf output. any AC line intersect does not affect its radio performance. Check and adjust RF power so to maintain proper output. some times more RF power generated at the output may cause interference. adjust Rf power..Even some unfiltered Noise getting the other end of the end may calso cause interference. Check for any Ripple voltages present at the output. Contact authorised service station for further Rectification. thank you shanth

Check your water inlet maybe there is a leaked that flows into the body going through the floor..

It is usually calcium-carbonate and lime.
Once the stuff gets into water lines, it can clog elbows and pipes and cause low water pressure.
If pressure is good, then clean out faucet aerators, and install water softener/filter
Generally a water-softener and filter can solve future problems.

If you have tankless water heater, then delime the unit:

If you have tank-type water heater, then clean out the unit

Before you do that remove shower head and see if you have flow without the head. The shower heads clog much more easily than the diverter valve

1-Remove aerator from end of faucet spout to check to make sure it is not obstructed by anything. Grit builds up there and causes flow to decrease , but it can be taken appart and cleaned out.

2-If you have a sprayer attachment to it sometimes the diverter goes bad. This sends water to spray head.

Cut water off remove handle with allen wrench and loosen collar on top to gain access to remove spout. after removing handle and collar you can pull up on spout or work it side to side easily to remove it.

In the middle at the bottom it has a removeable diverter that can be removed and replaced.

If it comes appart it will restrict water flow.

3- If you have to remove faucet to make sure no obstructions any where esle.

I hope this may be some help for you to have a starting point.

check the water line to the unit and take it loose from the solinoid there might be some trash in the line or calcium build up

If there is a filter on the unit, change it. If not, then sounds like the screen is clogging up. You will need to pull the unit out and remove the water supply line and take off the adaptor to access the filter screen and clean it...

You must make sure your water line isn't kinked. You may need to replace your saddle valve. Get rid of the self piercing type.

Your problem is a simple one.

1. Turn off water to faucet.
2. Place a towel(s) in the base of the sink(s) to prevent any parts from going down drain.
   
3. Remove the handle to the faucet. (single handle only)
   
4. If not a single handle then remove spout from faucet.
5. If a single handle remove cap carefully and any loose parts.
6. Gently turn spout side to side while lifting to remove.
7. You will see a hole with a very small valve where the water comes out to the spout on the base of the faucet.

1. Remove this valve (which is a backflow preventer) and replace.
2. Reassemble and test.
   

Problem solved.
