SOURCE: how to correct error code C-7 on my RTG-74PVN Rheem Pronto

I had the same problem and called the manufacturer. The error code C-8 was followed by the number 76. They told me to disconnect the thermostat/digital display from the main unit. This was fairly simple to do by removing the front panel. The unit works steady now without shutting down after a few minutes. The help desk told me that the main circuit board needs to be replaced for the unit to work with the display and that they would mail me one asap. At least we have hot water again.

SOURCE: "Jacuzzi j-400 series" hot tub- F1 code flashes on control panel

There are two things you can check, there is a tranformer that plugs into the main circuit board(usually a four wire plug). Unplug and check pins for good connection and then reconnect There are usually one or two fuses inside the control box mounted on or near the circuit board. Turn off power to spa and pull fuses and check continunity. This is a good start.

SOURCE: Bosch Nexxt 500 Plus Elect Dryer Error E01

Absolutely those dryer sheets are the root of all evil....I would also recommend a good vent brush to clean your dryer vent.
Follow these steps, it worked for me:
1. use a shop vacuum to clean out the dry vent or a vent brush.
2. Clean your lint filter with windex, hot water and and soft bristle brush.
If this doesnt work try running the until disconnected from the vent for a cycle to isolate the vent as your issue.

Cheers!

Low Flow errors are not necessarily real. They can be caused by improper adjustment or a defect of the pressure switch. Locate the pressure switch. Verify that the "switch" makes contact. Adjust the dial, reducing the distance the switch has to travel to engage. This will effectively lower the operating pressure required to operate. Keep adjusting until the unit stays on.

SOURCE: Repeat problem with FH error code (takes too long

FH error indicates that either you have no water coming into the washer, or very little water. Since you can see it filling, the error indicates low flow. A flow meter
in the unit detects if 10.5 gallons fills the tub within 8 minutes; yours must not be. This will turn off the inlet valves and the error code will be displayed. Check the following:

- Make sure you don't have a siphoning problem. This occurs when there is no air gap for the drain line at the standpipe. The standpipe is the drain pipe at the wall where the washer drain line is placed. With no air gap, a vacuum is created, and water will begin to drain from the wash tub prematurely. To prevent this from occurring, follow this advice:

•The standpipe should be 2 inches in diameter to allow a sufficient air gap between the top of the standpipe and the drain hose.
•The standpipe should be a minimum of 34" from the floor, and should not exceed 72 inches in height.
•DO NOT seal the top of the standpipe. Many consumers seal the standpipe in the belief that this will prevent overflows, or get rid of drain odors. This often creates more problems than solutions.
•DO NOT place the drain hose too far down into the pipe. Water stays in the drain trap area of the standpipe. If the end of the drain hose rests in this area, no air gap is created, and this can also cause siphoning. 4 to 6 inches is sufficient.
•The drain hose length must not exceed 10 feet in length. Excessive drain hose length can cause drain problems and back wash.
- Verify Drain Pump operation. Unplug the washer and take the lower panel under the door off by removing the three screws under the bottom edge. With the screws removed, the panel should drop down then come off. If it sticks, tap either side and it should come free. The pump is located directly under the wash tub in the front of the washer. Verify the electrical connections are good and that the pump is running. Open the pump access and remove, once you have all the water drained. Check the drain pump for foreign objects and debris. Check the pump impeller and make sure there's nothing caught in it. Items as small as toothpicks or cotton swabs have been known to stop this pump from working.


- Verify Flow meter operation and that the Pressure Switch hoses are intact and connected properly. Remove the three screws in the top panel along the back of the washer. With the screws removed, the panel should slide back, then, lift off. The flowmeter will be located on the left-hand side of the washer (facing from the front) between the inlet valve and dispenser. It's a small white plastic device with hoses attached. The pressure switch is located on the right-hand side of the washer in the rear. It is a round plastic device with electrical connections and a hose attached. There should be a tech sheet directly behind the panel or attached to one of the interior cabinet walls. Please refer to this sheet to learn how to perform diagnostics, how to locate the components mentioned, and the specific measurements required in determining if the components are good or bad.


"F/H" indicates that either you have no water coming into the washer, or very little water.

If you have NO water coming into the wash tub after 30 seconds the error code is displayed. Check the following:

- Inlet water valve may be clogged. Clean inlet screens if necessary.
- Make sure water taps are on.
- Check inlet hoses for kinks or clogs.

If you HAVE water filling the wash tub, and after 8 minutes, 10.5 gallons of water has been detected by the flowmeter, but there has not been a detected a Pressure Switch trip, the inlet valves are turned off and the error code is displayed. Check the following:

- Make sure you don't have a siphoning problem. Click the following link for instructions: http://www.fixya.com/support/r587481-prevent_washer_siphoning
- Verify Drain Pump operation.
- Verify Flowmeter operation.
- Verify the Pressure Switch hoses are intact and connected properly.

To access the Drain Pump - UNPLUG the washer and take the lower panel under the door off by removing the three screws under the bottom edge. HINT: Propping the front feet of the washer up can make access much easier. I use a couple small blocks of wood. With the screws removed, the panel should drop down then come off. If it sticks, tap either side and it should come free. The pump is located directly under the wash tub in the front of the washer. Verify the electrical connections are good and that the pump is running. If not, click on the following link to check the pump for obstructions:

I have a Jacuzzi J340 Hot Tub. I am having trouble with the heating. When the pump is on, the water circulates just fine. once the heater kicks on, it runs for about 10 seconds, then clicks to OH, and...


make sure the heating element isnt touching the casing inside the heating tube. if its an indoor tub, make sure the filtration cycles are not set to constant. constant filter cycles on an indoor tub will generate residual heat from the circ pump running 24/7, causing tub to heat past 104 degrees

Aqua Flo Flo Master won't start on low speed


Water flow error on hot tub means low water flow. This is not enough water flow to turn the system on.
Some motors do have a start capacitor on them. you can certainly check that or take it to your local motor repair shop and they can check that for you.

Balboa 52502 val 5m7


have you cleaned your filter recently. Sound like there may be a low flow error in low speed
either that or the start capacitor on your pump is bad and the pump will not come on in low speed unless you first give it a boost in high speed
anytime you ask for heat with insufficient flow there will be an error message

Control flashes oh


This code is for an OverHeat situation.
This could happen for a number of reasons. The most likely are either a clogged impeller inside the circulation pump, or a clogged cartridge filter.

Even if the filter looks clean, they only have 6 months recommended use in a residential hot tub before invisible debris start to clog them. Once the filter is clogged, the flow of water is greatly reduced. Once the water flow is reduced, the water flowing through the heating element starts to OverHeat due to being in contact with with the heater for too long.

Cut the power to the spa off, remove the filter element, reapply power to the spa, and check for the code. If it does not reappear, simply get a new filter element.

If the code reappears, clean out the pump impeller. and reset power again.

As a last resort, you might have to check the thermistor. Its rare, but a thermistor can fail and show a false high temp reading.

I just bought my hot tub, it shows ''FLO'' on the panel when i turn it on. I did every thing they say on the panflet but it still doesn`t work. Anything else i should do??


The problem is that the flow switch for your water heater is indicating no flow. Therefore your water heater will not operate. Without proper water flow your heater will burn up. Check that your valves are open. Check that your pump is running. Check that your filters are properly installed and not restricting flow. Check the wiring to your flow switch and make sure the flow switch operating properly (i.e. put a ohm meter across the contacts and see if you have continuity when the switch closes).

What does FL mean on my hot tub?? water doesnt circulate but is still sort of warm...


FL could be a code for low flow. If you have no circulation this sounds like it. If your pump runs and you have no flow you could have a problem with your pump. Or if you have the tub drained then it could be an air lock, if you open the drain valve till you get water out that should fix that. Also check to be sure the isolation valves are open under the spa. I hope this helps.

I have a 2004 great lakes hot tub with a balboa controler. My hot tub heats up fine when the pump runs on high but the temp light never comes on when the pump runs in low.


check to see that the flow switch is working properly, it may not have enough flow on low speed to allow the heater to turn on. Make sure your filter/s is/are clean. If you have a pressure switch instead of a flow switch, it may need to be adjusted or replaced.

Our artic spa hot-tub is showing HL in the panel and is not heating up as it should. Everything else seems fine. Why?


HL is normally a "high limit" fault. If your filter is clean and you have sufficient flow, you may have a faulty high limit sensor. It should be mounted on the heater itself. The high limit sensor shuts the heater off if it senses excessively hot water. Check to see that you have sufficient flow, clean the filter, and make sure the filter pump is running. If everything else is running properly, you may have to replace the high limit sensor.
