Trouble Shooting Your Chilipepper Hot Water Pump Models CP6000 and CP2011
This is a simplified trouble shooting guide for your hot water demand system.
Before beginning this guide make sure the outlet you have plugged the
Chilipepper into has power. Check by plugging a lamp or appliance into the
outlet and trying it. Beware of outlets that have the garbage disposal plugged
into them. They are usually only on if the switch for the disposal is turned on.
Make sure also that the hot and cold water supply valves are on and run the
hot and cold fixtures for a few moments to be sure no air is trapped in the

Trouble Shooting Your Chilipepper Hot Water Pump
If you are having a problem with your Chilipepper demand system please review
these trouble shooting procedures.
They cover all of the common types of problems.
When I Push the Button
Check for power at the outlet.
If your unit is being installed under the kitchen sink do not
assume that you can use the outlet being used by the garbage disposal.
In most cases the outlet is controlled by a wall mounted switch and so
power is only present when the disposal is operating.
If there is power at the outlet then the only other thing you need to do
is to short the control wires together momentarily.
If there is power at the outlet and the Chilipepper is in good working
condition, something will happen!
If nothing happens the unit needs to be returned to us for service or
The microprocessor based technology in the control circuit of the CP6000
allows you to determine in most cases just what is wrong or not wrong with the unit.
The Pump only runs for a moment and shuts off
To activate the Chilipepper requires the two control wires make contact,
and then break contact. In other words, the unit will not start up until
you release the button.
The voltage on the control wires is 5 volts at less than 1 milliamp.
The microprocessor monitors the control wires and the temperature sensor
built into the pump.
If the control wires are connected and released, the microprocessor will
first check the temperature of the water inside the pump.
If the water temperature is less than 96 degrees F., then the processor
will start the pump and begin to monitor the temperature for an
increase, and when it detects an increase in temperature it will shut
the pump off.
If the water temperature is more than 96 degrees F., then the pump will
run for 1/4 second and stop. This is to alert you to the fact that
hot water is already present.
Every time you try to start the pump, it will only run for 1/4 second
and stop if the water has not cooled to below 96 degrees F.!
If the pump behaves like the water is already hot, but you know the hot
water pipe has cooled off water in it, then turn on the cold water tap
for a minute or two to flush out any potential warm water, and try it
Also turn the sensitivity knob fully clockwise for the least
sensitivity for the test.
If it still behaves as though there is already hot water then the unit
will need to be returned for service or replacement.
The pump runs for two short bursts and repeats every 15 to 20 seconds.
If you are using a remote control system such as X10 or others
electrical noise on the power lines can cause the unit to not work
Sometimes the remotes can get stuck in the on position. Your
Chilipepper will run for two quick 1/4 second jogs and repeat every 15
to 20 seconds. This is to let you know that the control wires are
shorted, or whatever they connect to is malfunctioning.
Usually pressing the "off" button will reset the relay in the remote
Power line electrical noise can even cause the remote to start the
Chilipepper, although it is very rare.
To solve the problem you need to find the source of the noise and
install a noise filter between the offending device and the outlet that
the offending device is plugged into to prevent the noise from getting
into the power lines. X10.com carries such filters, although the X10
website is difficult to use.
The X10 noise filter works with 120 volt 60 Hz outlets...a normal
outlet....and will handle up to 5 amps. It's called an
It's an XPPF filter at X10.com. It costs about $20.00.
Some typical noise producing items are florescent light fixtures and
electric brush-type motors used in vacuum cleaners and garbage disposals.
