PROBLEM |
| PROBABLE CAUSE |
| REMEDY | |
Inconsistent beverage level in | 1. | Improper water pressure |
| Check operating water pressure to | |
server/dispenser |
|
|
|
| the brewer. It must be between 20 |
|
|
|
|
| and 90 psi (138 and 620 kPa). |
| 2. | Brew valve |
| Test the brew valve. Refer to test | |
|
|
|
|
| outputs on page 48. Turn the valve |
|
|
|
|
| on for 30 seconds and collect the |
|
|
|
|
| water dispensed from the spray- |
|
|
|
|
| head. Repeat the test several times |
|
|
|
|
| to confirm a consistent volume of |
|
|
|
|
| dispensed water. If not consistent, |
|
|
|
|
| check the valve, tubing and spray- |
|
|
|
|
| head for lime buildup. |
| 3. | Bypass valve |
| If bypass is being used on the in- | |
|
|
|
|
| consistent brewing recipe, test the |
|
|
|
|
| bypass valve. Refer to test outputs |
|
|
|
|
| on page 48. Turn the valve on for |
|
|
|
|
| 30 seconds and collect the water |
|
|
|
|
| collected from the funnel. Repeat |
|
|
|
|
| the test several times to confirm |
|
|
|
|
| a consistent volume of dispensed |
|
|
|
|
| water. If not consistent, check the |
|
|
|
|
| valve, tubing and fittings for lime |
|
|
|
|
| buildup. |
| 4. | Lime buildup |
| Inspect for lime buildup that could | |
|
|
|
|
| block the tank, tank fittings, tubing, |
|
|
|
|
| valves and sprayhead. |
| 5. | Brew volume adjustment |
| Adjust the brew volume, calibrate | |
|
|
|
|
| sprayhead and bypass as required |
|
|
|
|
| to achieve the desired volume for |
|
|
|
|
| each brew cycle. |
