TROUBLESHOOTING GUIDE

PLEASE NOTE: The following corrective actions may be performed by the spa

owner. If the trouble cannot be corrected in the steps below, please contact your

authorized Marquis spa dealer for service. (Improper servicing by an unauthorized

service provider or spa owner could result in damage not covered by the warranty and

could cause serious injury.)

EQUIPMENT WILL NOT OPERATE

• Check the control panel LCD window for diagnostic code.

• Check the circuit breaker on the main circuit panel.

• Check the condition of the power cord.

INADEQUATE JET ACTION

• Be sure the shut-off valves are completely open.

• Open the jets by turning the jet face to allow for maximum water flow.

• Check for obstruction or restrictions at suction guard(s) or filters, such as

leaves.

• Check that the water is at proper level, 2/3 up the Vortex skimmer

opening(s).

• Inspect the filter cartridge(s) for dirt and debris.

NO HEAT

• Check temperature displayed in the LCD window for desired temperature setting.

• Inspect the filter cartridge(s) for dirt and debris.

• Check that the water is at proper level, 3” above skimmer opening(s).

• Check HEAT MODE to be certain spa is not in SLEEP MODE.

• Lower ambient temperatures may result in heat loss.

NOTE: Do not expect instant hot water from the jets. It will take the heater 12-24

hours to heat the water to the temperature you desire.

LIGHT DOES NOT WORK

• Press the LIGHT pad on the control panel.

• Reposition the light bulb in the socket. (See REPLACING LIGHT BULB.)

• Replace the light bulb with similar component only.

LCD DIAGNOSTIC MESSAGES

The advanced technology built into the spa allows it to perform a number of self-

diagnostic system checks and it can display a variety of messages in the LCD

window on the control panel.

HH: Over heat protection. The system completely shuts down. In such a

condition, DO NOT ENTER THE WATER. Contact your dealer for service.

OH: Overheat protection. If a malfunction occurs and the spa water reaches

43°C, the system completely shuts down. In such a condition, DO

NOT ENTER THE WATER. Turn off all power to the spa and contact your

dealer for service. Several conditions could lead to overheating, for example,

low water level, shut-off valves closed while heater is on, dirty filter, and

restriction in the plumbing lines. After the power if turned back on, the spa will

not restart itself until the water temperature within the spa drops to a lower,

predetermined temperature. As a double safety feature, a secondary high-limit

sensor shuts the system off if the water temperature in the heater housing

reaches 118°F (48°C). In this case, the spa may be restarted by pressing any

panel pad after the water has cooled to 110°F (42°C). If the switch trips

repeatedly, do not use the spa and contact your authorized dealer for service.

IC: Ice. Potential freeze condition detected.

SA: Spa is shut down. Sensor plugged into sensor “A” jack is not working.

Sb: Spa is shut down. Sensor plugged into sensor “B” jack is not working.

Sn: A sensor has malfunctioned. If alternating with spa temperature, it may just

be a temporary condition. If flashing by itself, spa is shut down. Contact your

dealer for service.

HL: A significant difference between temperature sensors has been detected.

This could indicate a flow problem. Check water level in spa and refill if

necessary. If water level is okay, make sure the pumps have been primed.

LF: Persistent low flow problems. Heater is shut down, but other spa functions

continue to run normally. Check water level and refill if necessary. Contact your

dealer for service.

dr: Possible inadequate water, poor flow, or air bubbles detected in the heater.

Spa is shut down for 15 minutes. Check water level and refill if necessary.

If okay, check that pumps have been primed. Press any button to reset.

dY: Inadequate water detected in heater. Spa is shut down. follow directions for

dr” message.

MAINTENANCE

WEEKLY MAINTENANCE

1. Removing Debris

Remove any debris and leaves from the Vortex skimmers and suction

guard(s) on the inside of the spa. Blocked intakes can impede the flow of

water through the jetting system.

2. Water Level

Replenish the water level if necessary so that it is approximately two-thirds

up the Vortex skimmer opening. (See STARTING YOUR SPA.) Low and

high water levels can damage your spa. It is important to check your water

level often.

MONTHLY MAINTENANCE

1. Filter Care

We cannot stress enough the importance of a clean filter for proper water

filtration. Dirty filters can restrict water flow, cause hazy water, and prevent

your chemicals from working properly. Dirty filters can also cause low flow

from jets, poor water clarity and sensors to activate error codes. It is

important to clean filters regularly. Many water treatment products clear or

clarify the water by clumping microscopic particles and minerals together so

that these larger particles can be effectively trapped in the filter. A filter

clogged with debris and calcium deposits does not trap particles properly.

The Maintenance Reminder on the spa-side Control Panel indicates a CL

every 30 days to remind you to clean your filter.

EVERY THREE TO FOUR MONTHS

Leakage Detection

Open the equipment door and check for signs of water leakage around the

pump(s). Pump seals wear out over time, especially with improper water

chemistry. Early detection of pump seal failure can significantly reduce repair costs.

Ozonator Operation

The ozonator functions whenever the system is running on filter or clean up

cycles. Check to see if the bulb is lighted. The end cap of the ozonator should

glow if functioning properly. If not, the bulb has burned out. Contact your dealer

for service.

Draining and Filling the Spa

On average, a spa needs to be drained every three to four months. After months

of continually adding chemicals to the water and introducing body oils and

lotions, the water can be difficult to manage and chemicals are not as effective

as usual. You may also notice excessive foaming. More frequent draining may be

required depending on use.

Draining the Spa

A. Turn off the power to the spa.

B. Open the equipment compartment (see EQUIPMENT DIAGRAM).

Remove the hose bib cap from the connection and attach a hose.

C. Open the drain valve. Gravity causes the water to drain out of the hose.

D. When the spa is empty, close the drain valve and remove the hose.

Reinstall the hose bib plug.

NOTE: Keep the drain valve closed at all times except when draining the

spa (do not rely on the cap to stop the flow of water). Not doing so could

result in damage to the drain valve due to freezing water.
