Troubleshooting

This section provides troubleshooting information in the form of an easy to read table. If a problem occurs during the first operation of a new fryer, recheck Installation and Maintenance procedures.

To isolate a malfunction, proceed as follows:

  • Clearly define the problem (or symptom) and when it occurs.

  • Locate the problem in the Troubleshooting table.

  • Review all possible causes. Then, one-at-a-time, work through the list of corrections until the problem is solved.

Problem Cause Solution
Product Color Not Correct: A. Too Dark (some batches)

  • Temperature programmed too hot.

  • Breading product too far in advance

  • Done alarm ignored for more than 20 seconds.

  • Wrong product button pressed.

  • See Diagnostic Mode D 10; if temperature settings have been changed, have the controls reintialized.

  • Bread product just before frying.

  • If the fryer hasn’t been used since the problem batch, see Information Mode 4 H; for more information on this problem, see Information Modes 5 U, 6 U, 7 R, or 8 R

  • Be sure to press the correct product button; if the fryer hasn’t been used since the problem batch, see Information Mode 4 B to see what product button was pressed
B. Too Dark (all batches)

  • Temperature probe out of calibration.

  • Peanut oil too old.

  • Peanut oil too dark.

  • Faulty probe “E6”.

  • See Diagnostic Mode D 1 to adjust color of product.

  • Check temperature probe calibration; see Checking Temperature Probe Calibration Section; if less than 15 degrees off, have probe calibrated; if more than 15 degrees off, replace probe.

  • If peanut oil is smoking or has burnt taste, change peanut oil.

  • See Diagnostic Mode D 2; Change peanut oil if controls indicate it should be changed.

  • Filter peanut oil or change peanut oil.

  • If probe can’t be recalibrated, have probe replaced.
C. Too Light (all batches)

  • Temperature probe out of calibration.

  • Slow fryer heat-up/recovery.

  • Oil usage wasn’t set for new for

  • peanut oil

  • See Diagnostic Mode D 1 to adjust color of product. Check temperature probe calibration; see Checking Temperature Probe Calibration Section; if less than 15 degrees off, have probe calibrated; if more than 15 degrees off, replace probe.

  • If fryer hasn’t been used since the problem batch, see Information Mode 4 C; for more information on this see Information Modes 5 S, 6 S, 7 P, or 8 P.

  • If fryer hasn’t been used since problem batch, see Information Mode 4 B to see what product was selected.

  • See Diagnostic Mode D 7 (Continued) to see how many times the Cook Cycle was stopped before the end of the cycle.

  • Use fresh or thawed product; see Diagnostic Mode D 5 to see if the controls sensed any frozen or overloaded batches.
Dryness of Product

  • Moisture loss prior to cooking

  • Over-cooking the product

  • Time of Cook Cycle set too long

  • Wrong product button pushed

  • Low operating pressure

  • Use fresh product.

  • Cover product with plastic wrap, reducing evaporation.

  • Done alarm ignored for more than 20 seconds; if the fryer hasn’t been used since the problem batch, see Information Mode 4 H; for more information on this problem, see Information Modes 5 U, 6 U, 7R, or 8 R.

  • See Diagnostic Mode D 10; if time settings have been changed, have the controls reintialized.

  • If fryer hasn’t been used since problem batch, see Information Mode 4 B to see what product was selected.

  • Check pressure gauge reading. Check for pressure leaks.

Burned Taste

  • Burned peanut oil flavor.

  • Peanut oil needs filtering.
