Why is water refill indicator on when reservoir is full?

ChoccyBar,

THANK YOU. You're answer was so helpful. I have the XP7230 and all of the sudden had exact same problem, machine wouldn't not register a full tank. After reading this I checked the floating piece and saw that it was not floating with a full tank like it is supposed to. Had to obstruct it to keep it afloat as well, and voila, it worked.

Ahh... what a relief to have my machine working again. Coffee has never tasted so good.

Did your Jet Clean System used to work, but now rejects the razor and flashes a red indicator that your reservoir is empty when it is not?

The reason is that the liquid level sensor is full of gunk (you don't want to know what the gunk is made of). You can easily clean this yourself and restore normal operation. Here's how:

1. Remove the razor and reservoir. Leave it plugged in.
2. Press the start button and when the holder hits the bottom and stops, immediately pull the plug before it comes back up.
3. Turn the unit over and clean off the gunk you can see with a Q-Tip.
4. Fill the cleaned reservoir beyond the line (almost to the top) with hottest tap water and place it on a towel on your counter.
5. Mix in 1/8 teaspoon of dishwasher detergent. Do not use Dawn or other dish detergent. It must be the type you use in your dishwasher! (Trust me on this).
6. Lower the unit onto the reservoir and let it soak for at least 20 minutes.
7. Hold the reservoir down on the towel by depressing the release buttons and pull and put the cleaning unit in and out of the reservoir 20 or more times to flush out the crud.
8. Refill the reservoir with clean, hot water and do the pull - push trick again many times. Rinse and refill the reservoir with hot water and do this again 2 more times until the water is clear and there is no debris to be seen in the water.
9. Remove the reservoir and allow the cleaner to dry thoroughly. Depending on the humidity where you do this, drying can take from several hours to an entire day. A hair dryer on the part you cleaned with the Q-Tip may help, but time will still be needed.
10. Assemble and try it. It should work like new. If it does not work properly, (mine acted like it was jammed) don't worry, it is likely not completely dry inside. Remove the reservoir and wait for it to completely dry before trying again.

Have fun!

Use the correct descaling agent
Only citric acid-based descalers are suitable for descaling the SENSEO
machine. This
type of descaler descales the machine without damaging it. For the correct amount,
see under 'Descaling procedure' below. Each descaling mixture can be used only once.
After use, the descaling mixture is no longer active.
We advise you to use the special SENSEO
Descaler (HD7012/HD7011/HD7006).
Read the instructions on the package of the descaling agent.
Never use a descaling agent based on mineral acids such as sulphuric acid,
hydrochloric acid, sulphamic acid and acetic acid (e.g. vinegar). These descaling
agents may damage your SENSEO

coffee machine.
Descaling procedure
1 Mix 50 grams of citric acid with 1 litre of water in a measuring jug. Stir until
the powder is completely dissolved.
2 Fill the water reservoir up to the MAX indication with the descaler mixture.
Then put the water reservoir back into the coffee machine. (Fig. 3)
Note: Not all SENSEO
machine types have a water reservoir with a capacity of
1 litre. If you have a SENSEO

machine with a smaller water reservoir, repeat steps
2 to 6 with the remainder of the mixture without filling the water reservoir up to
the MAX indication.
3 Press on/off button 3. (Fig. 10)
The machine is ready for use when the indicator light lights up continuously.
4 Place the 1-cup holder h with a used coffee pod in it in the coffee machine.
Close the lid and make sure it is properly locked.
Note: Always put a used coffee pod in the pod holder when you descale the
machine. This pod serves as a 'filter' to prevent the sieve or hole in the pod holder
from getting clogged with scale residue.
5 Put a bowl with a capacity of at least 1500ml under the spout to collect the
descaling mixture (Fig. 8).
6 Press the 2-cup button hhand let the machine operate. Repeat this until
the water reservoir is empty. (Fig. 25)
Never interrupt the descaling process!
7 Repeat steps 1 to 6. Replace the used pod with another used pod to filter out
the scale residue.
Note: To descale properly, you have to use 2 litres of descaling mixture.
Never descale the SENSEO
coffee machine with the lid open. Make sure the lid is
properly locked.
8 Rinse the water reservoir with tap water. Fill the water reservoir up to the
MAX indication with tap water and repeat steps 3 to 6.
Note: Do not refill the water reservoir with used hot water or the used descaling
mixture.
9 Fill the water reservoir with fresh tap water up to the MAX indication again
and repeat steps 3 to 6 once more.
Note: Always rinse the machine by letting it empty two full water reservoirs.
10 Remove the used pad and clean the pod holder after descaling to prevent the
sieve or hole in the centre from getting clogged.

sure,. sounds like a good plan to me.,. you may want to also inspect to be sure it's not broken or otherwise cracked. and fill the the respective level line (when engine is cold or hot). You may be able to simply use a 50-50 prestone blend or full strenght if the existing coolant is low on antifreeze depending upon your needs climate-wise...

Water reservoir state, is it full?
If not refill it with proper coolant, run it again with open cap until the water bubbles out, turn off motor, fill the reservior again then close the cap. Let it cool for 15 minute, start the bike and see if it still overheats.
If it does then the coolant is not circulating as it suppose to, check for any indicator of leak or oil or water in your reservoir. Note of caution, never open your reservoir when it is HOT.
Good enough?

Problem was a stuck float in the small water reservoir to the rear left of the unit.. Remove top and left hand side panel. Small reservoir can be seen at the bottom left. Remove small screw and slide off the cable assembly above. You should then see into the reservoir and the float. Clean float and reservoir and reassemble.

There is no full indicator for the reservoir, so when refilling, it will overflow (behind the right front tire) when it is full. Most assume that it is cracked or leaking.

Spoke to my maintenance engineer at work and he said that most of these appliances work by using float switches. After stripping down and drying out the previous day decided to refill reservoir with water and letting drain back in refilled again 15 mins later till no more water could go back in. Then emptied water reservoir and let the water drain back out into reservoir. Think this must have dislodged the float switch and all seems back to normal.

I think I have the answer.

On Yahoo Answers Blue Rizla Girl put up the idea that the sensor is some form of hydrometer. (i.e. floats in salty water sinks if not salty enough)

Based on this thought I postulated that the sensor is some form of hydrometer float in a tube with perhaps an optical sensor.

If this is correct why is it not working?

Is it because the float is stuck at the bottom of the tube, perhaps by some food debris? If so how can we fix it?

This is what I did on my Hotpoint FWD60:-

I took the salt filler cap off. There was no salt in the reservoir as it has been a problem for months, and I was only refilling it when dishes were not coming clean.

I poured 2 litres of hot water into the salt reservoir.

I then put the empty machine on the intensive 65 degree wash, half load and with the reservoir cap still OFF.

When finished I filled up with salt and HEY PRESTO the salt light is OFF!!!!

Just hope it stays that way until the reservoir really needs refilling.

While I was down on my hands and knees I took the opportunity to clean the filters in the sump. They do get full of bits!

I also flushed the sump by dashing a couple of cups of hot water into it and then bailing it out with a small yoghurt pot. I repeated this until the water in the yoghurt pot and the sump no longer had any signs of bits in them. (Dashing = vigorously pour)

I was amazed at how many bits I got out, especially considering I had given the machine a good clean in the past 6 weeks.

I even got part of a paper label!

So there we have it, try it out and report back.

Check the instructions which are freely available from www.miele.co.uk or the relevant site for your country. Browse to the current models and you should find the PDF for your model. For non-current models, instructions are under the link "Customer Support".

In general, the instructions are as follows:
If the water in your area is very soft and constantly lower than 0.7 mmol/l (4 °d) you do not need to add dishwasher salt. The water softener must, however, still be programmed to correspond to the water hardness level in your area. (The salt indicator light will still come on, but should be ignored).

Important: Before filling the salt reservoir with dishwasher salt for the first time, you must fill it with approx. 2 litres of water to enable the salt to dissolve. Once the dishwasher has been used, there is always sufficient water in the reservoir.

Inadvertently filling the salt reservoir with powder or liquid dishwasher detergent always leads to serious damage to the water softener. Make sure you have picked up the correct packet of dishwasher salt before filling the salt reservoir!

Only use special coarse grained dishwasher salt for reactivation. Do not use other salts such as cooking salt, agricultural grade or gritting salt. These may contain insoluble additives which can impair the functioning of the water softener.

To refill:
* Remove the lower basket and unscrew the salt reservoir cap.
* Fill the reservoir with approx. 2 litres of water (first use).
* Place the funnel provided over the salt reservoir and carefully fill with salt until the reservoir is full. The salt reservoir holds approx. 2 kg of salt depending on the brand used.

As the salt reservoir is filled, displaced water will overflow.
* Clean any excess salt from around the reservoir opening and then screw the cap on again firmly.
* Run the "Pre-wash" programme immediately to remove any traces of salt water from the cabinet.

For the Miele, the salt reservoir is usually under the bottom basket, the cap is usually grey in colour. [Only the latest models have the refill cap in the door itself].

You should be able to find dishwasher salt just about anywhere, I've even found it in Malaysia, sold at good ol' Tesco!! Brands of salt include Calgonit (Finish) & Somat.
