First time start up

There isn't a low cost solution for this problem. The cause of the fill up problem is that the vapor canister is damaged and would cost about $800 to replace. When you are filling with gas, the fumes from the empty tank are expelled through the vapor canister which is designed to capture the hydro carbon molecules to prevent air pollution. The design of the Accent fuel system allowed gas to get into the canister when the fuel tank was over filled which damaged the system. The alternative is to just take your time filling the gas tank. The pump which will sense the back pressure from the slow venting will shut off repeatedly but with patience you can fill the tank. Just wait about 5 seconds each time after the pump turns off before starting to fill again.

You need to know the size of the tank before you can figure pump up time from empty to full. It sounds like you have a bad tank check valve. A bad check valve typically causes the motor overload to trip when starting.

I have same problem most of time was filling gas.
will change the evaporator or tank valve this weekend will post the results.

Check the fuel pump. Happens lots of times, Fill up tank and car wont start. Listen for the hum from the gas tank when key is turned to run postion.

Tell me when you fill up how far do you go before it stops,,then how far does it go the second time and the 3rd time ,,Do the times get longer each time,, if so then your problem isent a big deal.
The problem you might have is that the return fuel pipe from the engine returning fuel back in to the tank,, and the TANK breather pipe which has to let air in as you cannot take fuel out and not let air back in ,,so it causes a vacuum in the tank... So check the breather before any thing else .. OR dont fill it up any more than the first click of the pumps .
Let me know how you get on Ron

I recently encountered the same issue. First off, with the external tank installed is there an icon on the display panel indicating the tank is installed?

No? Then the two sensors are not picking up the magnets in the the "arms" on the back of the tank. It's a poor design for sure, on my unit the tank does not sit flush enough to the back of the AC, if I held the tank firmly to the back the icon would come on. I just used a bit of cardboard at the bottom of the support tray to press the tank firmly to the back of the AC.

Theory is as the external tank fills up, water will run into the "arms" and raise the magnets tripping the switch which tells the unit it needs emptying. But the magnets in the arms are not strong enough if they are not close enough to the sensors. So my cardboard solution lasted only one tank.

I ended up getting some flat neodymium magnets (that I scavenged out of a hard drive), and taped to the sensor that had the gap. I wouldn't recommend doing this to both sensors since it would eventually overfill, only one sensor needs to "trip" for the compressor to turn off.

If you answered yes to the first question (the bucket icon is there), then it's most likely the pump not working on the internal reservoir, or something related to that. Can't help you there...

If it leaks while filling it is likely any of the several fittings or it may be the 3 port check valve attached to the incomming water line. These are routinely installed backward. The idea is that when hooked to an external water supply the water goes only to the faucet and when using the tank, water can only go from the tank to the faucet. You cannot be hooked to external water and use the tank.

Any cracks in the tank should be obvious.

Use teflon plumbers tape on all screw fittings or will leak for sure. Hose clamps are also a necessity.

don't insert nozzle in fill hole so deep. It is not getting the air it needs to vent out while your fillinh the tank. Also start off slow on filling the tank, so that the air will start coming out while gas is going into your gas tank. like is said, the tank isnot venting fast enough, to let the gas come into the tank.

water fill light stays on how can I fix this problem ?There is no water in the internal tank or the external tank.Please help

Dear ziba1--posted the same problem two days ago and it doesn't appear to be on the site yet. Anyway, picked away at this again today (literally took the machine apart) and found the problem to be a clog in the drainage system. This explains why your external tank will not fill and why there is a leak--the drip tray under the compressor is not draining due to the clog in the drainage system. I fixed this simply by taking a narrow device and gently scraping out the drain hole of the drip tray (which is located just below the compressor...the compressor is located on the same side as your air filter). After successfully cleaning out this drain, I proceeded to flush the water out thoroughly with water. Give it a try--worked for me. I had all but given up and had already set up an appointment to have it serviced. Cheers
