Water is not getting cold
Problem	Cause	Corrective Action
Compressor is warm or hot & fan will not shut off	Relay connection to compressor is loose Relay is defective Refrigerant charge problem Condenser fins in front of the fan are covered with debris	Push relay onto compressor Replace relay Contact service agent Remove debris with compressed air or vacuum (may have caused overload, relay or compressor defect)
Compressor is room temperature. Fan runs continuously	Possible open overload or relay Possible defective compressor Condenser fins in front of the fan are covered with debris	Replace overload and relay Compressor needs to be replaced, contact service agent Remove debris with compressed air or vacuum (may have caused overload, relay, or compressor defect)
Compressor is room temperature & fan will not run.	Power lost to outlet Open cold control Wire terminal not plugged into cold control	Restore power to outlet Replace cold control Locate correct terminal & plug into cold control
Compressor or inside of water cooler is hot. Fan is not running	Fan is blocked by a tube Fan is defective	Remove tube from fan Replace fan
Compressor is making a loud knocking or grinding noise	Compressor is defective	Compressor needs to be replaced. Contact service agent
Water runs out of bubbler continuously
Problem	Cause	Corrective Action
Water cooler is an EZ, HTV, or electric eye series water cooler and water runs even when the power cord is not plugged in	Solenoid or solenoid diaphragm is defective	Replace solenoid. (To verify: while water is running, unplug the power cord. If the flow does not stop immediately, replace the solenoid)
Water cooler is an EZ, HTV series water cooler and water stops immediately every time when you unplug the power cord from the outlet	Press bar is sticking & holding micro-switch down	Replace push bar, or repair the cause of the sticking press bar - such as the basin hanging on the mounting bracket for EZ model, or the press bar screw too tight on the HTV model
Water cooler is an EHF, WC, HAC, or EMABF series water cooler	Press bar adjustment screw has not been adjusted properly Regulator is not stopping the water	Refer to manual & adjust press bar screw clockwise until flow stops Replace regulator, could be caused by sand or similar residue - consider adding filter
Water cooler or fountain model other than previous listed	Regulator is not stopping the water	Replace regulator, could be caused by sand or similar residue - consider adding filter
Water won't flow intermittently
Problem	Cause	Corrective Action
Water cooler was manufactured prior to 2001 & water is very cold	Sensing wire on the cold control has vibrated out of the bulbwell partially Cold control is out of calibration Bulbwell has detached from the evaporator coils Condenser fins in front of the fan are covered with debris	Push sensing wire down in the bulbwell Replace cold control Evaporator needs to be replaced - contact service agent Remove debris with compressed air or vacuum (may have caused overload, relay, or compression defect)
Water quality problem (taste or odor)
Problem	Cause	Corrective Action
Water has a taste or odor problem	Install used plumbers putty or other sealant when connecting water supply Installer used a commercial grade stainless steel braided flex line to connect water supply to water cooler Water has bacteria or sulfur content	Remove sealant & use Teflon tape or compression fitting Remove stainless steel braided flex line & replace with appropriate supply line Contact your local water department & have water tested & add appropriate filter. Water cooler may need to be flushed with food grade sanitizer
Water stream is too low
Problem	Cause	Corrective Action
Stream is too low after initial installation of the product	Water pressure is lower than factor test conditions Press bar adjustment screw has not been adjusted for EHF, WC, HAC, or EMABF series water coolers Solenoid will not open up all the way on EZ, HTV, or electronic eye models Strainer screen is plugged with debris Water cooler has an added filter that is restricted	Remove sealant & use Teflon tape or compression fitting Refer to manual and adjust press bar adjustment screw Replace solenoid Clean or replace strainer screen Replace filter
Water stream is too high
Problem	Cause	Corrective Action
Water stream is too high	Water pressure is higher than factory test conditions Shut off valve is not open all the way causing a back pressure Bubbler or orifice is partially restricted with mineral deposits, causing back pressure (similar to placing your thumb partially over the end of a garden hose)	Refer to manual & adjust regulator screw counter clockwise to desired height Open shut off valve all of the way Clean or replace bubbler or orifice
No Water Flow
Problem	Cause	Corrective Action
Water cooler is an EZ, HTV, or electric eye operated model	No power to outlet Wire disconnected from solenoid Power cord to water cooler is open (compressor & fan will not run) Water shut off valve not open Regulator valve defective Kinked water line internally Water is freezing up in the evaporator	Restore power to outlet Find correct wire & replace on to solenoid Replace power cord Open shut off valve Replace regulator Locate affected line & remove kink Refer to freeze up section of "water won't flow intermittently"
No water flow on all other water coolers/fountains	Water shut off valve not open Regulator valve defective Kinked water line internally Strainer screen is plugged with debris Water is freezing up in evaporator	Open shut off valve Replace regulator Locate affected line & remove screen Clean or replace strainer screen Refer to freeze up section of "Water won't flow intermittently"
