Fridigaire wash cycle selection problem

Please help with the resolution of the problem. The wash cycle selection doesn’t work. I can select lower rack, or rinse cycle. None of the other cycle seem to work. Try to reset the power by using circuit breaker helps sometimes where I can select the cycle, but not always.
Is there a specific part which I need to replace ? How easy is it to replace ? Is there anything I can do before I try to replace the part ?

Frigidaire Dishwasher - Model # PLD2850REB1.

Thank you for the reply in advance.

hi Chris,

Thanks for the reply. Is it the control panel ? if so, I can easily replace the panel or is it the touch button panel on the front ? Which do you think is the problem ?
Thanks in advance.
